Esclarmonde’s Collective

The murder of beloved Friar Jordi thrusts his adopted son—friar and reluctant scholar Theo—into a world of deception. Ancient texts, hidden identities, a clandestine organization, and the suppressed legacy of a forgotten Christian sect rise from the shadows, pulling Theo toward a truth buried since the days of the Cathars.

Theo bands together with an unlikely group of Brown University students and their professor. Troubled by dreams of a fierce heroine from the Albigensian Crusade, they find themselves drawn into a centuries-old conspiracy. Their search leads them from an Ivy League library to the mountains of Montserrat and deep into the Vatican’s hidden chambers.

From the shadows, orchestrating her own brand of justice for Friar Jordi’s murder is Fox—a razor-sharp protector. When a deadly inquisitorial unit closes in on Theo and his friends, loyalties begin to fracture. To save the sacred manuscript at the heart of the mystery, Theo must confront betrayal, challenge his faith, and face the truth of who he is.

The past isn't over. It's waiting to be remembered.

A murder. A vanished sect. A secret the Church would kill to protect.
