In a world where wealth buys life, and human "Benes" are cultivated for their organs, Summer's 21st birthday gift is a ticking time bomb.

Born into the opulent world of BeneCorp, Summer has always resented the company that provides her family's immortality. She has a secret: she loves Glenn, her family's long-term Bene, like a brother. He's not a tool; he's family. But when a congenital heart defect threatens her life, her father, Orlando, makes an irreversible decision: he buys her a new Bene, Erick, a man who sold himself to atone for a tragic past.

Now, with her health failing and the stark reality of her future looming, Summer is caught in a moral maelstrom. How can she save herself if it means ending someone else's life? As she forges a dangerous connection with Erick and a desperate plan to save Glenn, she is forced to confront the dark truth of a world that treats people as property.

Can Summer escape her fate without sacrificing her humanity? Or will she be forced to become a willing participant in the system she has always despised?
