"You have until midnight. After that, all deals are off. And your daughter? She works for me until every cent is paid back. With interest." Aria never imagined her father's secrets would cost her freedom. One desperate phone call is all it takes for her world to shatter. A debt she never knew existed. A bargain she never agreed to. And a man who doesn't forgive, doesn't forget, and never loses. Cassian Romano is Chicago's most feared mafia king. Cold. Calculating. Untouchable. When her father fails to repay what he owes, Cassian takes the only collateral left. Her. Aria expects cruelty. She expects punishment. What she doesn't expect is the way her pulse betrays her when his dark eyes hold hers. The way her breath falters when his hands steady her. The dangerous flicker of something almost human beneath his ruthless exterior. She should hate him. She should fear him. Instead, she finds herself drawn to the very man who owns her fate. In a world where power is everything and mercy is weakness, desire becomes the most dangerous debt of all. Because some debts are paid in blood. Others are paid in surrender.
