Neighbors Gwen, Aimee, and Lisa share more than playdates and coffee mornings on their tranquil street in East Bethesda. They confide their deepest secrets, navigate the challenges of motherhood together, and provide a support system that seems unbreakable. Then Gwen’s husband is found murdered after one of their weekly Friday night dinners, and the peaceful quiet of their cul-de-sac shatters. The seemingly idyllic world of the three close-knit friends becomes a web of deception, betrayal, and revenge.

Beckett, If you’re reading this, well, you know the last-letter drill. You made it. I didn’t. Get off the guilt train, because I know if there was any chance you could have saved me, you would have. I need one thing from you: get out of the army and get to Telluride. My little sister Ella’s raising the twins alone. She’s too independent and won’t accept help easily, but she has lost our grandmother, our parents, and now me. It’s too much for anyone to endure. It’s not fair. And here’s the kicker: there’s something else you don’t know that’s tearing her family apart. She’s going to need help. So if I’m gone, that means I can’t be there for Ella. I can’t help them through this. But you can. So I’m begging you, as my best friend, go take care of my sister, my family. Please don’t make her go through it alone. Ryan

A family on a remote island. A mysterious woman washed ashore. A rising storm on the horizon. Dominic Salt and his three children are caretakers of Shearwater, a tiny island not far from Antarctica. Home to the world’s largest seed bank, Shearwater was once full of researchers. But with sea levels rising, the Salts are now its final inhabitants, packing up the seeds before they are transported to safer ground. Despite the wild beauty of life here, isolation has taken its toll on the Salts. Raff, eighteen and suffering his first heartbreak, can only find relief at his punching bag; Fen, seventeen, has started spending her nights on the beach among the seals; nine-year-old Orly, obsessed with botany, fears the loss of his beloved natural world; and Dominic can’t stop turning back toward the past, and the loss that drove the family to Shearwater in the first place. Then, during the worst storm the island has ever seen, a woman washes up on shore. As the Salts nurse the woman, Rowan, back to life, their suspicion gives way to affection, and they finally begin to feel like a family again. Rowan, long accustomed to protecting her heart, begins to fall for the Salts, too. But Rowan isn’t telling the whole truth about why she set out for Shearwater. And when she discovers the sabotaged radios and a freshly dug grave, she realizes Dominic is keeping his own dark secrets. As the storms on Shearwater gather force, the characters must decide if they can trust each other enough to protect the precious seeds in their care before it’s too late—and if they can finally put the tragedies of the past behind them to create something new, together.
