High school teacher Brindle Montgomery and rancher Trace Jericho have been inseparable friends for as long as either can remember, and on-again, off-again lovers for years. As rebellious as they are stubborn, they have always been perfectly content with their no-strings arrangement, each insisting they want nothing more. Then Brindle comes home from a trip to Paris with a baby bump, and everything they thought they had quietly settled comes undone. The news sends Trace's wild, reckless heart into a tailspin, while Brindle is left second-guessing whether she has just made the biggest mistake of her life. Caught between the easy heat they have always shared and the daunting weight of what comes next, the two must reckon with feelings they have spent years refusing to name. Set in the horse country of Oak Falls among the sprawling, meddling Montgomery and Braden families, this is a story about two headstrong people who know each other completely yet have never dared risk more than a fling. With a surprise pregnancy forcing their hand, Brindle and Trace have to decide whether friendship and desire can grow into the kind of love that lasts.
