The Breakaway by Jennifer Weiner

 Abby is in her 30s. She's working as a dog walker with no plan for the future. Her boyfriend Mark thinks they should move in together. And while Mark is a great catch and loves her, the thought of living together doesn't thrill her.So when her friend Lizzie asks her to lead a group of cyclists on a tour from NYC to Niagara Falls, she thinks this is the perfect opportunity to get away from her real life and figure out what comes next. But when she goes to NYC to greet her group, she discovers that her mother (with whom she has a very prickly relationship) has signed on--as has the dashing Sebastian, a hottie that Abby had a one-night stand with years earlier. What could go wrong?

There are some real characters on the tour. Some drama. And a lot of soul-searching. Jennifer Weiner does know how to tell a compelling story.
