This is the fourth book in the Rose Hill series, all about single dads who “find their happily ever afters in a rugged lake town, nestled in the Rocky Mountains.” In Wild Card, Sebastian is a pilot with smoldering chemistry with his new roommate, Gwen—who also happens to be the ex-girlfriend of his estranged son. If he ever hopes to repair the relationship, she’s strictly off limits. But how long can they deny the sparks flying between them?
