The book is set on the Princeton campus during Easter weekend in 1999. The story involves four Princeton seniors, both friends and roommates, getting ready for graduation: Tom, Paul, Charlie and Gil. Tom and Paul are trying to solve the mystery contained within an extremely rare, and mysterious book, the Hypnerotomachia Poliphili, which was an incunabulum published in 1499 in Venice, Italy; it is a complex allegorical work written in a modified Italian language frequently interspersed with material from other languages as well as its anonymous author's own made-up words.
Tom, the narrator, is the son of a professor who had dedicated his life to the Hypnerotomachia Poliphili. Throughout the novel, he struggles between being fascinated by the book and trying to pull away from the obsession that drew a rift between his father and his mother and is now causing discord between him and his girlfriend, Katie Marchand. Paul Harris is a young scholar who is writing his senior thesis on the Hypnerotomachia Poliphili and has spent all four of his undergraduate years studying the book and is on the edge of solving the book's mystery. His thesis advisors, Richard Curry and Vincent Taft, were friends and later rivals of Tom's father; Taft and Corelli found, stole, and concealed documents that provided clues to decode the mysterious book.
The title refers to a cipher that the characters find was used to encode a hidden message in the Hypnerotomachia, which leads to a secret vault in Florence, Italy of books and art that the author, Francesco Colonna, hid to protect them from Girolamo Savonarola's bonfire of the vanities. It also turns out that Paul's friend Bill Stein and his thesis advisor Vincent Taft were conspiring together to steal Paul's thesis and claim credit for it, and the sealed vault of treasures. They were murdered by Paul's wealthy but unstable benefactor Richard Curry to prevent this from happening. In a struggle with Curry that leads to a fire breaking out at Ivy Club, a Princeton eating club of which Gil is the president, Tom escapes but Paul and Curry are assumed to perish. Five years later, Tom, who is still traumatized and has had a failed engagement with another woman, receives an authentic ancient (and unknown) Botticelli canvas in the mail with a mysterious return address in Florence, Italy. He packs and heads off to meet Paul again.
The book has been well received by critics, with the New York Times Book Review calling it "the ultimate puzzle book", and several others comparing it positively to The Da Vinci Code. It received an aggregate score of 74 out of 100 (based on 17 reviews) on the review aggregator Metacritic.
