When the guy Lorylyn Porter thought was the love of her life tells her he's engaged, her world collapses. It doesn't matter that she married somebody else five years ago, or that she still keeps in touch with a fling from a summer on Martha's Vineyard, or that she fantasizes about another guy she might love more than all of them.
As she fights to move on from the news, write a dissertation on her own theory of love, and become the person she wants to be, her past and present love stories collide alongside those of her roommates: Zibby, who's had two weddings, but only one her family knows about; Jansen, whose developing relationship with one of her closest guy friends will force her to choose either what they have or a future that might not exist with the most important guy in her life; and Kylar, who loves three guys but can't seem to get things to work with any of them.
Amid ghosts from the past, conflicting feelings, and blurred lines, the girls will discover that no matter how much you love a guy, sometimes that heartbreaking moment of clarity comes along when you realize the best part of the relationship is over, and you don't want the rest of his life.
