In Break Wide the Sea, New York Times bestselling author Sara Holland's new novel, a young woman cursed with a fatal heartbreak-induced sickness must race against time to find a cure and protect her family legacy from the ancient finfolk that would destroy it, the fiancé that would kill her for it, and the boy who would love her if she forsook it.

In the treacherous waters surrounding Kirkrell, sailors hunting magic whales live in fear of the finfolk—bloodthirsty sea fae who sink ships and curse bloodlines. Nineteen-year-old Annie, as heir to the city's preeminent whaling company, is determined to carry on her parents' life's work. But she keeps a secret from everyone: she's cursed to transform into a monster, with scales spreading up her arms and claws growing from her fingertips.

Her fiancé August offers comfort, but their love falls apart when Annie discovers his plan to take over the company. Desperate, Annie makes a deal with Silas Price, a young captain rumored to be half-finfolk. He says he knows how to break the curse—but only if Annie promises to stop the practice of whaling forever.

As Annie, August, and Silas sail north, Annie wrestling with her family's legacy, the threat of the finfolk and August's ambitions increasingly force her to put her trust in Silas. Yet Silas has secrets of his own, and they might be the most dangerous of all.
