Three adult sisters reunited at their childhood home must confront a shared tragedy in The Irish Goodbye - the devastatingly beautiful debut novel from Heather Aimee O'Neill.

It's been years since the three Ryan sisters were all home together at their family's beloved house on Long Island. Two decades ago, their lives were upended by a tragic accident on their brother Topher's boat that drove him to suicide. Now, the Ryan women are back for Thanksgiving, but each carries a heavy secret.

The eldest, Cait, is still holding guilt for the role no one knows she played in the boat accident, when she rekindles a flame with her high school crush, Topher's best friend. Middle sister, Alice, has been thrown a curveball threatening her career and, potentially, her marriage. And the youngest, Maggie, is finally taking the risk to bring the woman she loves home to her devoutly Catholic mother.

When Cait invites a guest to Thanksgiving dinner, old tensions boil over and new truths surface. Far more than a family holiday will be ruined unless the sisters can find a way to forgive themselves - and each other.
