Thirty-three-year-old Abby Stern is mostly at peace with her plus-size body and is on track to marry her childhood sweetheart, Mark. Yet Abby can’t escape the feeling that something isn’t right…or the memories of one mind-blowing night spent with a man named Sebastian two years ago. So when Abby gets a last-minute call to lead a group bike trip, she’s happy to have time away from Mark and a chance to make up her mind. But on the first day, Abby is shocked to see Sebastian in the tour group. And then there’s a last-minute addition to the trip --- Abby’s mother, Eileen, whom Abby blames for a lifetime of insecurities she’s still trying to undo. Over the next two weeks, strangers become confidantes, hidden truths come to light, and a teenage girl with a secret will unite all the riders in surprising ways.
