His first novel, Twenty Something: The Quarter-life Crisis of Jack Lancaster was published in 2006 by Gerald Duckworth and Company Ltd. The book won him the 2006 infamous literary Bad Sex in Fiction Award, which he accepted in person announcing "I hope to win it every year".  He is the youngest author to have won the somewhat dubious honour. This book has also been translated into Vietnamese by Le Thu Thuy, under the title "Tung qua tuoi hai muoi", and was well received by young Vietnamese readers. Overall the novel was well received, drawing critics' comparison with Sue Townsend, Helen Fielding and Tony Parsons.
