Ava Sinclair is desperate. Her father's rare illness is bankrupting her, and time is running out. In a last-ditch move, she joins Velvet Circle-an elite underground agency where powerful men pay fortunes for one night of total control. Xavier Blackwood doesn't do love. He's a billionaire who treats women like transactions: hot, hard, gone by morning. No strings. No repeats. Until Ava steps into his world. One contract. Fifty thousand dollars every time he calls. No feelings. No questions. Just her body on demand. But obsession creeps in fast. His hands can't get enough of her curves. Her moans start sounding like surrender. And the money can't drown out the truth they're both avoiding: What happens when "just sex" becomes something neither can walk away from? A raw, steamy, addictive billionaire romance packed with dominance, possession, and heat that burns everything down.
