|Born||James Paul Czajkowski|
August 20, 1961
Chicago, Illinois, USA
|Pen name||James Rollins, James Clemens|
|Occupation||Veterinarian, journalist, novelist|
|Education||Doctor of Veterinary Medicine (D. V. M.)|
|Alma mater||University of Missouri in Columbia, Missouri (1985)|
|Genre||Action-adventure, thriller, fantasy, mystery, techno-thriller|
He attended Parkway South Junior High School and then graduated from Parkway West Senior High School in Ballwin, Missouri, in 1979. His undergraduate work focused on evolutionary biology. He graduated from the University of Missouri in Columbia in 1985 with a doctorate in veterinary medicine (D. V. M). Soon afterward, he moved to Sacramento, California, where he established his veterinary practice, licensed July 24, 1985.
In an August 16, 2012 interview, he told SLM's Jeannette Cooperman:
For 20 years my paycheck was coming from my veterinary degree and my writing was my hobby, and I thought it would be really cool to flip that around. Veterinary medicine is much harder. It's a 14-, 16-, 18-hour-a-day job. I owned my own practice, had 24 employees. I couldn’t get away, that was the biggest thing. In the 10 years I ran my own practice, I had three weeks of vacation total. I started writing during my lunch hour at the clinic—dogs barking, cats meowing—so now I can write anywhere.
Now, he's flipped that equation: "Once a week I spend about eight hours spaying and neutering trapped feral cats for the Sacramento Council of Cats. All I do with my veterinary degree now is remove genitalia."
Rollins found the authors of the Doc Savage series inspirational as a youth and acquired an extensive collection of the popular 1930s and 1940s pulp magazine stories. Rollins was fascinated by stories of the exploits of Howard Carter and his discovery of the tomb of the ancient Egyptian pharaoh, King Tutankhamun (King Tut); this true-life tale later inspired Rollins' novel Excavation, in which the main character, archaeologist Henry Conklin, and his nephew Sam discover a lost Inca city in the mountains of the Andean jungle that contains a treasure—and a curse. He also enjoyed L. Frank Baum's Oz series, Edgar Rice Burroughs' Tarzan novels, and C. S. Lewis' Chronicles of Narnia. Additionally, he was inspired by Jules Verne and H. G. Wells, whose works he used as a springboard for creating similar contemporary novels filled with what he refers to as "the three M's of fiction: magic, mayhem, and monsters".
Czajkowski sold his first novel, Witch Fire (1999), under the pen name James Clemens, through Terry Brooks' publisher. Brooks had been one of the judges for a writing contest at the Maui Writers' Conference in Maui, Hawaii, in which James had entered a manuscript he had recently completed.
Beneath the ice at the bottom of the Earth is a magnificent subterranean labyrinth, a place of breathtaking wonders—and terrors beyond imagining. A team of specialists, led by archaeologist Ashley Carter, has been hand-picked to explore this secret place and to uncover the riches it holds. But they are not the first to venture here—and those they follow did not return. There are mysteries here older than humanity and revelations that could change the world. But there are also things that should not be disturbed—and a devastating truth that could doom Ashley and the expedition: they are not alone. The caverns are inhabited by an entire subterranean ecosystem of primitive mammals—some intelligent, others savage, all beyond the reach of today's knowledge.
In Peru, low in the Andes, Dr. Henry Conklin discovers a 500-year-old mummy that should not be there. While deep in the South American jungle, Conklin's nephew, Sam, stumbles upon a remarkable site nestled between two towering peaks, a place hidden from human eyes for thousands of years. Ingenious traps have been laid to ensnare the careless and unsuspecting, and wealth beyond imagining could be the reward for those with the courage to face the terrible unknown. But where this perilous journey ends—in the cold, shrouded heart of a breathtaking necropolis—something else is waiting for Sam Conklin and his exploratory party. A thing created by Man, yet not humanly possible. Something wondrous...something terrifying...a mysterious metal known only as el Sangre del Diablo (or Devil's Blood), known only to the most ancient of Incas and a secret sect of Dominican friars who have already killed and died to protect its secrets.
Four years ago, all contact with a U.S. medical-scientific expedition in the wilderness of the Amazon basin suddenly ceased; the 30-man team was declared lost and likely dead. Now, one of its members staggers into a Christian mission but dies within hours. He carries identification: he is Gerald Clark, ex-Special Forces. Two years before the expedition, while in Iraq, the CIA operative's left arm was amputated at the shoulder. Photographs of the corpse and fingerprints reveal that the arm has grown back perfectly. Unable to comprehend this inexplicable event, the United States CIA establishes a special team to return to this impenetrable secret world of unforeseen perils and to follow the dead man's trail. On arrival, they enlist Nathan Rand, the son of the lost researchers' team leader. A mysterious plague, that threatens the Earth's entire population, leads back to Gerald Clark. This means the lost expedition's destination, which holds the key to the cure, must be discovered at any cost. But the nightmare that awaits Rand and his team of scientists and seasoned U.S. Army Rangers dwarfs any danger they may have anticipated.
Ice Hunt (2003)Edit
After an Alaskan game warden rescues a man from a crashed plane and saves him from subsequent attack by foreign soldiers, his ex-wife's piloting skills take them all to the man's intended destination, a US research base on the Arctic ice, set up following the discovery by advanced ice-penetrating sonar of a derelict Russian scientific base buried within a massive iceberg, Ice Station Grendel, where the personnel all died decades earlier. A Russian submarine carrying the son of the station's former commander also approaches, ostensibly to retrieve the bodies found by the Americans. Both sides know the station contains vastly important scientific secrets, worth fighting for, but neither side knows quite how the other will fight, or how Grendel itself will complicate matters. In an atmosphere of mistrust and fear, the Alaskans and the scientist overseeing the sonar project have unexpected roles to play, while in the midst of terror, unexpected allies, and betrayals, neither side can afford to lose.
Indiana Jones and the Kingdom of the Crystal Skull (2008)Edit
In 2008, Random House commissioned Rollins to write the novelization of Indiana Jones and the Kingdom of the Crystal Skull (2008), the eponymous, American adventure science fiction film. This is the fourth film in the Indiana Jones franchise, created by George Lucas and directed by Steven Spielberg.
Altar of Eden (2009)Edit
The story starts outside the Baghdad Zoo immediately after the Battle of Baghdad (2003). After being decimated during the 2003 invasion of Iraq, the floodgates have been opened for the smuggling of hundreds of exotic birds, mammals, and reptiles to Western nations. However, this crime hides a deeper secret. Years later, a Louisiana state veterinarian, Lorna Polk, is flown to a wrecked fishing trawler in the Mississippi River delta basin by the United States Customs and Border Protection (CBP). The crew is missing, but the boat holds a live cargo: a caged group of exotic animals. Initially, Polk assumes it is part of a black market smuggling racket. Then. she discovers disturbing deformities that make no sense. Also, the animals all share disturbingly heightened intelligence. To uncover the truth about the origin of this strange cargo and the threat it poses, Polk must team up with a man who shares a dark and bloody past with her, now an agent with the CBP.
SIGMA Force SeriesEdit
The SIGMA Force is a fictional division of the U.S. DARPA program. The chief operatives in SIGMA combine highly trained military skills with specialized scientific knowledge. The Force's purpose is to investigate and to secure sensitive information that could be a threat to the United States; its functions are a combination of counter-terrorism, research, and covert operations. Following the first book, Sandstorm (2004), the SIGMA Force headquarters moves into the sub-basement of the Smithsonian Institution in Washington, D.C.. These novels are intended to be read in chronological order.
Book 0: Deep Fathom (2001)Edit
Ex-Navy SEAL Jack Kirkland surfaces from an aborted underwater salvage mission to find the Earth burning. Solar flares have triggered a series of gargantuan natural disasters. Earthquakes and hellfire rock the globe. Air Force One has vanished from the skies with America's president on board. Now, with the U.S. on the narrow brink of a nuclear apocalypse, Kirkland must pilot his oceangoing exploration ship, Deep Fathom, on a desperate mission miles below the ocean's surface. There, devastating secrets await him—and a power of an ancient civilization. And it will forever alter a world that's already racing toward its own destruction.
This book was not originally part of the SIGMA Force series, but its characters were frequently featured in the series' later novels.
Book 1: Sandstorm (2004)Edit
The first book of the SIGMA Force series, Sandstorm (2004), starts with Commander Painter Crowe and Cassandra Sanchez attempting to thwart a computer hacker who is putting the United States in danger. Meanwhile, in the British Museum, a private collection is destroyed; the cause cannot be explained. The DARPA director, Vice Admiral Tony "The Tiger" Rector, instructs SIGMA to send a small team to investigate. Their quest takes them into the Arabian Desert, to a long-buried threat that may bring about the end of the balance of power.
This novel introduces SIGMA Force and a mysterious opposing group, referred to as the Guild, who appear in some of Rollins' future SIGMA Force novels. The main character, Crowe, is intelligent, fearless, resourceful, and romantic.
Book 2: Map of Bones (2005)Edit
The magi brought gold, frankincense, and myrrh to the Christ child; their bones may bring destruction to the world, if they are allowed to remain in the hands of the thieves who stole them, for these bones may not be bones at all. They may be something much more terrible and deadly, as Map of Bones (2005), Rollins' second SIGMA Force novel, suggests.
Book 3: Black Order (2006)Edit
In Black Order (2006), SIGMA Force team members risk their lives to get to the heart of one of mankind's greatest mysteries: the origins of life itself. This novel features Dr. Lisa Cummings (first introduced in Deep Fathom), who begins a relationship with one of the team.
Book 4: The Judas Strain (2007)Edit

Crowe takes part of the team to Oslo, while an unexpected phone call from a traumatized Rachel Verona has Grayson rushing all over Europe, ending up in a high-security prison in France. Crowe and his team fly over the Arctic Circle to land in Spitzbergen. Ultimately, it is revealed that the characters are dealing with an ancient, fungal parasite that was discovered and used first by the Egyptians and then, later, by eleventh century Celts and Druids as a bio-weapon.
Book 6.5: The Skeleton Key (2011)Edit
In this short story "Seichan is ripped out of the Sigma series for an adventure all her own". She and a young urban explorer, who has tattooed on his body a map of the Catacombs of Paris, awaken in a Paris hotel after having been kidnapped and drugged, to find deadly electronic collars fastened around their necks. They are tasked to rescue the kidnapper's son, "who has fallen under the sway of the nefarious leader of an apocalyptic cult". The trail leads them into "the dark necropolis beneath the City of Lights". Seichan and her guide must battle the clock, as the cult leader has wired the catacombs with bombs.

The team attempts to track down a lost map, journeying – among various farflung places – to Fort Knox and the grave of Meriwether Lewis. Rollins refers to secret codes used by Thomas Jefferson and Lewis. The coded message leads Crowe to John Trumbull's painting depicting the presentation of The Declaration of Independence.
Book 7.5: Tracker (2012)Edit
In the medieval heart of Budapest, Captain Tucker Wayne and his war dog, Kane, rescue a mysterious woman fleeing three armed men. They are after the secret she holds, which will unlock a terrible treasure steeped in blood and treachery, tied to a crime going back to the fall of Nazi Germany and a heritage of suffering and pain that reaches out from the past to wreak havoc today.

SIGMA Force movieEdit
Husband and wife production team Dino de Laurentiis and Martha Schumacher purchased the movie rights to SIGMA Force in 2010. Dino has observed: "James Rollins is a master storyteller. The Sigma Force series is rich with complex characters and thrilling action plots, and we can’t wait to turn this treasure trove of amazing stories into a great film franchise."
According to CinemaBlend: "The film won't adapt any of the six existing novels, but will tackle a brand-new story within the world with the aim of starting a franchise." Dino de Laurentiis died 10 November 2010, but Rollins, when interviewed by the Houston Chronicle's Murder By the Blog staff (aka "MurderBooks") on June 27, 2011, confirmed: "I spoke to Dino's grandson last month. He reported that a screenplay was well underway and that they are looking at a couple of different directors. So things are moving." As of February 25, 2019, the project is listed as "in development" at IMDB Pro.
The Banned and the Banished seriesEdit
Godslayer Book One: Shadowfall (2005)Edit
For 4,000 years, the people of the Nine Lands have lived peacefully under the guidance of their hundred gods. When the goddess Meeryn is murdered the peace is shattered, and Tylar de Noche – a defrocked knight who, as sole witness, is now sole suspect – must find the killer and prove himself innocent. Tylar turns to Delia, a priestess and love interest, and to Rogger, a thief wise to the ways of the criminal underworld. Slogging hither and yon for scraps of clues, the three begin to suspect that the supposedly pacific gods are in fact engaged in an ongoing struggle for power and control. The self-absorption of the gods and the apathetic ignorance of the people form stumbling blocks on Tylar's quest.
Godslayer Book Two: Hinterland (2006)Edit
Failed Shadowknight Tylar witnessed the death of a god, whose blood healed his deformities but branded him a Godslayer and a hunted criminal. In this second volume, Tylar's struggle for the truth is vindicated when he is officially reinstated as a Shadowknight.

But even Tylar's skill and magic cannot save the Citadel of Tashijan, ancient Shadowknight headquarters, for something foul lies at the heart of their Order. The Cabal has infiltrated the inner council and Tylar and his allies must flee for now there can be no refuge from evil.
Other Godslayer BooksEdit
On the FAQ section of his website, Rollins announces plans for further novels: "There are more plans for the Godslayer books. The working title for Book Three is God-Sword. Besides continuing the storyline, it will discover much more about Laurelle, her past, and her perilous journey to a god hidden in the heart of a volcano. God-Sword will finish the first trilogy. And there may be a second trilogy with many of the same characters."
On February 10, 2015, Rollins wrote in an AMA ("Ask Me Anything") on Reddit.com: "Third book is done; fourth is midway. Once the fifth is done, the entire series is slated for publication, each book coming out 6 months apart, starting with a re-release of the first two."
Collaboration with Rebecca CantrellEdit
Rollins collaborated with the mystery writer Rebecca Cantrell to write several works in the Order of the Sanguines series (comprising a trilogy published in print and digital formats, plus a number of short fiction e-books): City of Screams (2012), a novella set in Afghanistan; The Blood Gospel (2013); Blood Brothers (2013), an e-short; Innocent Blood (2013); and Blood Infernal (2015).
