"A married couple joins a week-long wilderness expedition to help them reconnect in this heartfelt companion novel to the viral TikTok sensation Out on a Limb"--High school sweethearts Sarah and Caleb Linwood have always been a sure thing. For the past seventeen years, they have had each other's backs through all of life's ups and downs, achievements, losses, stages, and phases. But Sarah has begun to wonder... Who is she without her other half? When she decides to take on a project of her own, a fundraising gala in memoriam of her late mother, Sarah wants nothing more than to prove to herself -- and to everyone else -- that she doesn't need Caleb's help to succeed. She's still her mother's daughter, after all. Independent and capable. That is until the event fails and Caleb uninvitedly steps in to save the day. The rift that follows unearths a decade of grievances between them and doubts begin to grow. Are they truly the same people they were when they got married at nineteen? Are they supposed to be? In a desperate attempt to fix what they fear is near breaking, Sarah and Caleb make the spontaneous decision to join a grueling hiking trip intended to guide couples through rough patches.
