"Thirty-four-year-old Abby Stern has made it to a happy place. She's got good friends, her bike, and her bike 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 her childhood sweetheart. Abby and Mark met at the weight-loss camp Abby's perpetually dieting mother, Eileen, forced her daughter to attend. 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 from New York City to Niagara Falls, 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 when she sees a familiar face in the tour group - Sebastian, the one-night stand she never thought she'd see again. To make things even worse, there's a last-minute addition to the trip - Abby's mother, Eileen, whom Abby blames for a lifetime of body shaming and 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 - while all of Abby's certainties about herself, her mother, and the nature of love are challenged."-- Provided by publisher.
