True to their family name, the Wilders of historic Rustler Mountain, Oregon, have an outlaw lineage and a wild nature to match. But when it comes to love, an untamed heart might know best . . .

Carson Wilder and Perry Bramble have been best friends forever, starting with their painful childhoods. As far as romance, Carson always knew he wasn’t good enough for her. And by the time they were grown, their bond was too important to risk messing up. Now, Carson is grieving the death of his wife. And like always, Perry is his rock. He can’t imagine life without her. But he may have to.

Perry has loved Carson since she was 7 years old. He never showed a hint of interest in her beyond friendship, but two decades later, he’s still the most important person in her life. Maybe too important. Inspired by the diary of an ancestor who left everything behind to come west as a mail order bride, Perry stuns Carson with a decision: She’s moving to a neighboring city to expand her florist business—and to find love and start a family.

Carson hates the idea, but he’ll do anything for Perry’s happiness. He’ll even help get her historic home fixed up for sale. She can stay with him at his ranch house on Outlaw Lake in the meantime. What ensues are dinners filled with laughter, dating app disasters—and Carson wondering why he’d look for another woman when the one he loves is right here. His answers may lie in the letters he finds from the man who married the mail order bride. . . . But can he finally gather the courage to be true to his wild heart—before it's too late?
