He inherited the empire. She inherited the debt. Neither expected to inherit each other. When Elena Vance's father dies suddenly, she expects grief — not a mountain of hidden debt and a mysterious key to a vault she never knew existed. Desperate and alone, she has no choice but to seek help from the one man who despises her family: billionaire heir Adrian Blackwood. Adrian built his empire from the ashes of his father's ruin — a ruin caused by Elena's father. Now she stands before him, offering the key that could unlock the truth behind the conspiracy that destroyed his family. He agrees to help, but on one condition: she becomes his — body, heart, and every secret she's ever kept. As passion ignites between enemies, Elena uncovers a sinister truth: her father was framed, the debt is a lie, and someone powerful is watching their every move. But the closer she gets to Adrian, the more she realizes — the greatest betrayal might not be in the past. It might be sleeping in the bed beside her.
