Wild Card by Elsie Silver
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? 28,000 users marked it as read this week, and it has a 4.2 average rating.
