Books First Ltd The rule of Four

The Rule of Four by Ian Caldwell and Dustin Thomason is a literary thriller that combines historical intrigue, academic mystery, and a coming-of-age story. Set at Princeton University, the novel follows two college friends, Tom Sullivan and Paul Harris, as they become obsessed with solving the centuries-old mystery of the Hypnerotomachia Poliphili, a Renaissance text filled with cryptic puzzles and hidden meanings. As they uncover secrets buried within the text, they find themselves entangled in a dangerous web of academic rivalry and dark conspiracies. Blending intellectual depth with suspense, The Rule of Four is often compared to The Da Vinci Code for its mix of historical secrets and modern-day drama.
