About to depart on his first vacation in years, Edward Wozny, a hot-shot young banker, is sent to help one of his firm's most important and mysterious clients. When asked to un-crate and organise a personal library of rare books, Edward's indignation turns to intrigue as he realises that among the volumes there may be hidden a unique medieval codex, a treasure kept sealed away for many years and for many reasons. Edward's intrigue becomes an obsession that only deepens as friends draw him into a peculiar and addictive computer game, as mystifying parallels between the game's virtual reality and the legend of the codex emerge..."A compulsively readable novel" - Iain Pears. "A genuine treat, with its sneaky plot and richly textured storytelling. It also moves so fast that readers won't realize how smart it is" - "San Francisco Chronicle". ""Codex" takes its place on the shelf [with] "The Name of the Rose", "Possession" and "A Case of Curiosities", and it's as entertaining as any of them." - "New York Times".
