His second chance is his only chance

Parker Drake wants exactly one thing—to fulfill his dream of becoming a doctor. Between his reputation as a rule-breaker and the six years that have passed since his first internship ended in disaster, he knows he’s only getting one shot at a second chance. He’ll do anything to put the past behind him and reach his goal…including work with the gorgeous ex-wife he’s never gotten over losing.

All work and no play make surgeon Charleston Becker a very happy woman. But when she’s tasked with mentoring her ex-husband through his second chance as an intern, her signature calm is put to the test. She’s not interested in re-hashing the heartbreaking circumstances that ended their marriage, and the six years that have passed haven’t made Parker less reckless. The last thing she’s willing to do is trust him—even if she does find him sexier than ever.

But familiarity breeds forgiveness, which then becomes a passion that threatens the careers Parker and Charlie have worked for. Can they turn their second chance into a happy ending? Or is history bound to repeat itself?

This steamy contemporary medical romance can be read as a standalone.
