Summary

The Hypnerotomachia Poliphili is one of the most complex books ever written. Coded in seven languages, it is a passionate love story, an intricate mathematical labyrinth, and a tale of Renaissance tragedy that has baffled scholars since it was first published in 1499.

Five hundred years later, Princeton student Tom Sullivan is haunted by the violent death of his father, an academic who devoted his life to unlocking the book's secret. With his roommate Paul, Tom discovers a long-lost diary that holds the key to the puzzle.

But when a fellow researcher is murdered only hours later, the two friends find themselves in great danger, working desperately to break the book's code and uncover a Renaissance tale of passion and blood, a hidden crypt, and secret worth dying to protect.
