For social worker Mallory Ward, working with at-risk youth is a calling. But when one of her clients is tragically killed, she finds herself at a crossroads. Despite long-held resentments toward her distant mother, Mallory retreats to her childhood home on the Rhode Island coast to contemplate her future. Instead, she's confronted by her past, not only in the renewed tensions with her mother but in the unexpected appearance of a familiar face -- and the wrenching losses that drove her away a decade ago. Helen Ward's home is filled with precious keepsakes from her patients, a testament to decades spent caring for the terminally ill. Her work has always come first, though, leaving little time to connect with her daughter. Over the years, the rift between them has become a chasm, so when Mallory appears unannounced, Helen sees it as an opportunity to repair their broken relationship. But hidden among Helen's mementos are the keys to her past... and a terrible secret that threatens to destroy the fragile new trust between them forever.
