Thirty-three-year-old Abby Stern has made it to a happy place. True, she still has gig jobs instead of a career, and the apartment where she´s lived since college still looks like she´s just moved in. But she´s got good friends, her bike, and her bicycling club in Philadelphia. She´s at peace with her plus-size body--at least, most of the time--and she´s on track to marry Mark Medoff, her childhood sweetheart, a man she met at the weight-loss camp that her perpetually dieting mother forced her to attend. Fifteen years after her final summer at Camp Golden Hills, when Abby reconnects with a half-his-size Mark, it feels like the happy ending she´s always wanted. Yet Abby can´t escape the feeling that something isn´t right...or the memories of one thrilling night she spent with a man named Sebastian two years previously. When Abby gets a last-minute invitation to lead a cycling trip from NYC to Niagara Falls, she´s happy to have time away from Mark, a chance to reflect and make up her mind. But things get complicated fast. First, Abby spots a familiar face in the group--Sebastian, the one-night stand she thought she´d never see again. Sebastian is a serial dater who lives a hundred miles away. In spite of their undeniable chemistry, Abby is determined to keep her distance. Then there´s a surprise last-minute addition to the trip: her mother, Eileen, the woman Abby blames for a lifetime of body shaming and insecurities she´s still trying to undo. Over two weeks and more than seven hundred miles, strangers become friends, hidden truths come to light, a teenage girl with a secret unites the riders in unexpected ways...and Abby is forced to reconsider everything she believes about herself, her mother, and the nature of love.
