She lives by the rules. He lives to break them.

Cassidy Bowman has strict rules to uphold her good-girl reputation: she doesn’t date the Wells Ranch locals, and she definitely doesn’t sleep with men she isn’t dating. But after a run-in with her ex-boyfriend—and a few too many drinks—she’s ready to buck those rules and allow herself one night of recklessness.

On the other hand, local cowboy Chase “Red” Thompson has never met a rule he didn’t love breaking. With a long-time crush on Cassidy, he’s more than willing to accept her offer of a one-night stand and her one condition: he must agree to never speak of it again.

That is until two pink lines render Cassidy’s entire rule book null and void. Cassidy isn’t looking for a relationship with the rough-and-tumble cowboy, and Red doesn’t need anyone to tell him he’s not good enough for the sweetheart of Wells Canyon.

So the two make another agreement—they’ll be friends and co-parents, nothing more. But as their carefully constructed boundaries begin to blur, Cassidy might just realize that perhaps some rules are worth breaking.
