Kira Liebert's brief taste of freedom beyond Vita Nova's wall shatters when Patrol soldiers seize young Teddy, dragging him back to face certain death. With no choice but to follow, she returns to the city that branded her a traitor-only to be captured and cast into the Confines, the brutal prison where the condemned await execution. She emerges from the darkness bearing two impossible burdens: a blue rose on her wrist and a new identity as Victor Devlin's secret daughter.

Deep in the wilderness of the Unregulated Zone, Ghost refuses to surrender another soul to Vita Nova's cruel ritual. A scarred and haunted man whose past with Devlin and Kira's mother holds secrets that could topple Vita Nova itself, he knows the true cost of inaction. With Will, Brack, and Grace at his side, he plans a desperate rescue attempt. One final chance at redemption that could cost him everything.

As the clock winds down and the city watches her every move, Kira finds herself caught between two fathers on opposite sides of the wall-one who claims her as his own and one who refuses to let her go. Because while some fathers demand sacrifice, others stand ready to sacrifice everything.

RANSOM is the heart-stopping conclusion to the Reverence trilogy that asks: when everything you love is at stake, what are you willing to sacrifice?
