Ex Libris

When Sarah Wilderman is forced into an internship for the digital archive project DORESPRE in Seville to redeem herself after cheating on her exams, she expects it to be a slow summer. Then the priests start getting burned alive, and to stop the killer, Sarah and her new boss, Patrick Bauer, must solve a century-old mystery. But the deeper they dive into the secrets of the Spanish Inquisition and the Vatican itself, the more they realize the danger they are in. Because the killer will do whatever it takes to keep the secrets hidden.

The Vatican has asked Dr. Patrick Bauer to investigate rumors that the boy could be the reborn Messiah. When he recruits his ex-lover and former partner, Sarah Wilderman, to look into the boy, they soon find themselves in a web of conspiracies and influences.

She's in love with Derry, a bright and charming math student, surrounded by friends, and her biggest worry is whether she wants to return to her old life as a student. But her peace is short-lived. After a horrific murder, Sarah becomes the target of a relentless killer. Her investigation pulls her into the depths of a decades-old mystery involving the disappearance of a group of brilliant mathematicians—once poised to revolutionize their field. They called themselves The Dumat Society.
