The Marriage Contract (O'Malleys Series, Book 1)

Teague O'Malley hates pretty much everything associated with his family's name. When his father orders him to marry Callista Sheridan to create a ''business'' alliance, Teague's ready to tell his dad exactly where he can stuff his millions. But then Teague meets his new fiancee, sees the bruises on her neck and the fight still left in her, and vows he will do everything in his power to protect her. Everyone knows the O'Malleys have a dangerous reputation. But Callie wasn't aware what that meant until she saw Teague. But the closer they get, the more trouble they're in. Because Callie's keeping a dark secret-- and what Teague doesn't know could get him killed.
