For Ester and the other freshmen, the new school year begins with a sense of promise. Yet, her respite is short-lived; the academy's gilded halls hide dark secrets. A student vanishes without a trace. Whispers of a shadowy presence echo after curfew. And the ever-watchful director seems to be hiding something far more sinister than bureaucratic secrets. What begins as a search for answers will soon twist into a fight for her very soul.

Thrust into the center of this mystery is Ester — a blue-haired girl marked by a recent, violent death she cannot explain. Driven by fragmented memories and a desperate need for the truth, she begins an investigation that draws her into a dangerous game. The line between hunter and prey blurs as she finds herself irresistibly drawn to the very darkness she seeks to unmask. In this treacherous path, her only anchors are her roommates — the principled Staysh and the spirited Camilla. But the most perilous connection of all may be the one that forms between the hunter and her quarry.
