An intimate and deeply moving coming-of-age novel about second chances and the inextricable bonds between lovers and friends.

The only love Ari has known is Morgan. Engaged and planning a life with him in New York, Ari is shocked when Morgan sits her down one rainy afternoon and tells her their decade-long relationship is over. They've been over for a long time now, he says--and Ari knows he's right.

Twenty-eight years old and suddenly alone, Ari throws herself into a new job in Boston, as assistant to a tech CEO. Wells is British, twelve years her senior, a devoted husband and father. He's also captivated by Ari, in a way neither of them can explain. Ignoring every warning signal from friends and their own instincts, they dive into a fiery affair, which becomes more dangerous as Ari finds herself intricately tangled with his wife, Leah.

Nothing can prepare Ari for the choices she must make as she tries to uncover what's right for herself, and for the people she can't let go. As a new path opens--a journey of lies and the twisted calculus of protecting them--Ari's second chance at happiness forces her to consider who she really is. Can you love someone without dragging them under? What does it take to start over again?
