Princeton, Good Friday, 1999. On the eve of graduation, Tom Sullivan and Paul Harris are closer than anyone has ever been to unlocking the Hypnerotomachia Poliphili, a Renaissance text shrouded in mystery for centuries. For Tom, the book is a connection to his late father’s obsession. For Paul, it is the key to his academic future.

When they uncover a long-lost diary that could solve the puzzle, it feels like the breakthrough they have been chasing. But within hours, a scholar tied to the text is murdered.

As the bodies and secrets pile up, Tom and Paul are drawn into a dangerous race against time. The Hypnerotomachia holds the answers they seek, but also the power to destroy them.
