A friendship is tested in this "thrilling" page-turner from New York Times bestselling author Elin Hilderbrand ( Us Weekly ). Madeline King and Grace Pancik are best friends and the envy of Nantucket for their perfect marriages, their beautiful kids, their Saturday night double dates with their devoted husbands. But this summer, something's changed, and if there's anything Nantucket likes better than cocktails on the beach at sunset, it's a good rumor. And rumor has it. that Madeline, a novelist, is battling writer's block, with a deadline looming, bills piling up, and blank pages driving her to desperation -- and a desperately bad decision; and that Grace, hard at work to transform her backyard into a garden paradise, has been collaborating a bit more closely than necessary with her ruggedly handsome landscape architect. As the gossip escalates, and they have the possible loss of the happy lives they've worked so hard to create, Grace and Madeline try mightily to set the record straight -- but the truth might be even worse than rumor has it.
