For jingle writer Kissie Mitchell, rules are all that stand between order and chaos. Determined to move on from a breakup and a stagnant life, she heads to Mystic Hot Springs—a resort in the remote town of Twin Hearts, Montana—for a getaway with her best friend before embarking on a new job in Seattle and a more exciting life. She's armed with a laminated list of rules to keep her heart safe and a simple plan: find a rebound guy, get lucky, put her ex behind her. Not part of her plan: the resort's sweet and smoking hot bartender, Andrew Trig. Trig, with his soulful brown eyes, thick beard, and Keanu Reeves good looks, is not no-strings-attached rebound material. He's sell-all-your-stuff-and-move-to-the-middle-of-damn-nowhere-for-him material. Kissie is determined to keep her distance, but when he offers to act as her wingman for the weekend after her best friend gets sick in exchange for her help convincing Mystic's owners not to sell the resort he loves, she can't refuse. The more time Kissie spends in Twin Hearts, she's charmed by the town, by Mystic, and by Trig. As the sexual tension between them steams up the windows more than the hot springs water, Kissie will learn some rules are made to be broken. When a single night calls into question everything she thought she wanted, she'll have to decide if a misunderstanding will send her running away, or if sometimes moving on means staying right where you are.
