In this debut, for fans of J. Courtney Sullivan and Mary Beth Keane, three adult sisters grapple with a shared tragedy over a Thanksgiving weekend as they try to heal strained family bonds through the passage of time.

It’s been years since the three Ryan sisters were all together at their beloved family home on the eastern shore of Long Island. Two decades ago, their lives were upended by an accident on their brother Topher’s boat: A friend’s brother was killed, the resulting lawsuit nearly bankrupted their parents, and Topher spiraled into depression, eventually taking his life. Now the Ryan women are back for Thanksgiving, eager to reconnect, but each carrying a heavy secret. The eldest, Cait, still holding guilt for the role no one knows she played in the boat accident, rekindles a flame with her high school crush: Topher’s best friend and the brother of the boy who died. Middle sister, Alice, has been thrown a curveball that threatens the career she’s restarting and faces a difficult decision that may doom her marriage. And the youngest, Maggie, is finally taking the risk of bringing the woman she loves home to meet her devoutly Catholic mother. Infusing everything is the grief for Topher that none of the Ryans have figured out how to carry together.

When Cait invites a guest from their shared past to Thanksgiving dinner, old tensions boil over and new truths surface, nearly overpowering the flickering light of their family bond. Far more than a family holiday will be ruined unless the sisters can find a way to forgive themselves—and one another.
