Mercenary Brady Hayes hated it when debts were collected. Especially when he was called to the Underworld. But when Lord Shar called him in asking him to protect his sister, Raven, he had no choice but to agree. What he didn’t know was that Raven would be a gorgeous bundle of demon easy to fall for or that her ex-boyfriend would want to make trouble. But then, Brady wasn’t known to back down from danger or abandon a beautiful woman, even if she was from the Underworld.
