When Valeria Moreau arrives at Saint Rosetta University, she expects rigorous academia, not a labyrinth of sin and secrecy. The elite students whisper of The Order of Saint Rosetta, a clandestine society that thrives on power, intellect, and forbidden indulgence. Drawn into its web by the enigmatic and dangerously charming Professor Cassian D'Arcy, Valeria soon discovers that beneath the university's scholarly facade lies a chilling legacy of betrayal, unsolved murders, and rituals that bind members in blood and desire. As her passion for Cassian ignites, so does her obsession with uncovering the truth—until she realizes she is not just investigating the Order; she is being groomed for something far darker. When a cryptic manuscript reveals that Saint Rosetta's most brilliant minds were sacrificed in exchange for influence, Valeria must decide: escape before she becomes the next victim, or embrace the darkness and take her place among the sinners.
