Jessy Gilchrest is a pack leader, cage fighter, and self-described bad-ass who robbed the Vampire King's castle on purpose: her younger brother is locked inside Poison Penitentiary, and the only way in is as an inmate. On her first day, she picks a fight with the warden and becomes the prison's most wanted target. Four of the deadliest inmates — a werewolf, a dragon shifter, a vampire, and a demon — step up to protect her, but their price is steep.

Jessy is an unapologetically aggressive, sarcastic, fiercely loyal alpha who sometimes outpaces her own plans. Her love for her brother is the emotional core of the series — it is both her greatest vulnerability and the source of her most impressive decisions.

Across three books Jessy rallies her unexpected allies, survives escalating threats from inside and outside the prison, uncovers a millennia-old family curse tied to her brother, and battles her way to freedom through Warden Blackwater, the god Hades, and her own dangerous father. The series leans into reverse-harem romance alongside action and supernatural intrigue, building to a complete resolution in book three.
