On her 25th birthday, Lily Carter has it all: a degree, a dream job, and a family who loves her. Then a stranger in a black suit walks through her parents‘ door with an 18-year-old contract. To pay for the heart transplant that saved her life, her father promised her to the Blackwood family. Now cold billionaire Damien Blackwood has come to collect. He wants a wife, he wants revenge, and he wants her father to pay for a crime from long ago. But the heart beating in Lily’s chest hides a secret that could destroy them both… or make him fall in love with the one woman he swore to hate.
