Macy Sorensen is settling into an ambitious if emotionally tepid routine: work hard as a new pediatrics resident, plan her wedding to an older, financially secure man, keep her head down and heart tucked away. But when she runs into Elliot Petropoulos—the first and only love of her life—the careful bubble she's constructed begins to dissolve. Once upon a time, Elliot was Macy's entire world—growing from her gangly bookish friend into the man who coaxed her heart open again after the loss of her mother...only to break it on the very night he declared his love for her.
