In this “intense and beautifully written tale of complex female friendship” (Rhys Bowen, New York Times bestselling author), two estranged friends are unexpected reunited in the Hamptons, forcing them to finally confront the terrible event that drove them apart.

When wealthy, impulsive Margot meets hardworking and steady Thea in the summer of 1967, the unlikely pair become fast friends, working alongside one another in a record store and spending every spare moment together. But after an unspeakable incident on one devastating August night, they don’t see one another for ten years…until Margot suddenly reappears in Thea’s life, begging for help and harboring more than one dangerous secret. Thea can’t bring herself to refuse her beloved friend—but she also knows she can’t fully trust her either.

Unfulfilled as a housewife, Thea enjoys the dazzling sense of adventure Margot brings to her life, but will the truth of what happened to them that fateful summer ruin everything? Testing the boundaries of how far she’ll go for a friend, Thea is forced to reckon with her uncertain future while trying to decide if some friends are meant to remain in the past.

Set in the dual timelines of 1967 and 1977, All the Summers In Between is at once “a taut, dynamic examination” (Lynda Cohen Loigman, author of The Wartime Sisters) of a complex friendship, a delicious glimpse into a bygone Hamptons, and a powerful coming-of-age story of two young women during a transformative era. You’ll want to “make room in your beach bag for this mesmerizing book” (Patti Callahan Henry, New York Times bestselling author).
