"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 uncrate and organize a personal library of rare books, Edward's indignation turns to curiosity as he realizes that among the volumes there may be hidden a unique medieval codex, a treasure kept sealed away for many years and for many reasons." "Enlisting the help of Margaret Napier, a passionate and brilliant medieval scholar, Edward discovers the strange history of the codex and the dark, intricate tale that lies within its pages. His fascination becomes an obsession that only deepens as friends draw him into a peculiar and addictive game with mystifying parallels between the game's virtual reality and the legend of the medieval codex."--Jacket.
