Textus Haereticorum, AJ Treloar

When archaeologist Alex Carey receives a cryptic Latin letter marked with an ancient symbol, he is drawn into a centuries-old mystery buried since the crucifixion—one that could shatter the foundations of Christianity. Pursued by a secret Vatican order willing to kill to keep the past buried, Carey teams up with brilliant student Claire Marlowe on a high-stakes race across Europe. Their target: the Textus Haereticorum, a lost archive of forbidden writings that threatens to upend two millennia of Church history. From ancient ruins to coded manuscripts, every clue brings them closer to a truth too dangerous to reveal—one that refuses to stay hidden.
