Meet the Geller sisters: Beck, Claire, and Sophie, a trio of strong-minded women whose pragmatic, widowed mother, Marti, will be dying soon and taking her secrets with her. Marti has ensured that her modest estate is easy for her family to deal with once she's gone––including a provision that the family's summer cottage on Mount Desert Island, Maine, must be sold, the proceeds split equally between the three girls.
Beck, the eldest, is a freelance journalist whose marriage looks more like a sibling bond than a passionate partnership. In fact, her husband Paul is hiding a troubling truth about his love life. For Beck, the Maine cottage has been essential to her secret wish to write a novel––and to remake the terms of her relationship.
Despite her accomplishments as a pediatric cardiologist, Claire, the middle daughter, has always felt like the Geller misfit. Recently divorced, Claire's secret unrequited love for the wrong man is slowly destroying her, and she's finding that her expertise on matters of the heart unfortunately doesn't extend to her own.
Youngest daughter Sophie appears to live an Instagram-ready life, filled with glamorous work and travel, celebrities, fashion, art, and sex. In reality, her existence is a cash-strapped house of cards that may crash at any moment.
Enter C.J. Reynolds, an enigmatic southerner ex-con with his own hidden past who complicates the situation. All is not what it seems, and everything is about to change.
