In the idyllic small town of Tucker, Vermont, life flows at a rhythmic pace for thirty-nine-year-old pediatrician Paige Pfeiffer. But when Mara O'Neill, Paige's best friend and medical partner, inexplicably commits suicide, Paige's comfortable world is shattered. Temporarily caring for Mara's newly adopted baby daughter while she comes to grips with her grief, Paige clings to hope that, in time, she'll understand why Mara chose to end her life, and Paige's own orderly life will return.
