Sometimes no matter how hard you try, some things cannot be explained. Sixteen-year-old Samuel, son of devout cleric, has endured shame and prejudice his entire life. Although he is destined to become clergy too, he longs for an ordinary life in the whitelands away from demons and holy roots. When the mayor claims to have captured a mute demon girl, Samuel is forced to become her caretaker. But as Samuel gets to know the prisoner, he finds her not to be very demonlike. Instead, she is intelligent, meek, and an exceptional artist. Despite her seeming goodness, some more concerning things cannot be explained. Samuel is hard-pressed to reconcile her uncanny strength and speed, missing arm, ambiguous gender, and the mysterious scars covering most of her body. Samuel forms a deep attachment to the girl with predator eyes and violent outbursts, against his father's advice. Their friendship could turn into something more. But when Samuel discovers the mayor's dark intentions, he must decide whether to risk his own execution by setting her free or watch as the girl is used as a pawn in a dangerous game of oppression, fear, and murder.
