K.

In 1918 America, a woman named Sidney makes a radical choice: she turns down marriage to become a nurse, determined to forge a useful life on her own terms. But independence proves more complicated than she expected when she takes in a mysterious lodger known only as 'K.', a man with no first name, no past, and no intention of explaining either. As Sidney navigates the rigid hierarchies of early twentieth-century medicine, forming an unexpected connection with the brilliant young surgeon who runs her ward, the shadows from K.'s history begin to close in. What begins as a quiet tale of a woman claiming her own destiny evolves into something far darker: a story about the secrets we keep, the identities we abandon, and the pasts that refuse to stay buried. Rinehart, the writer Time magazine called 'the American Agatha Christie,' weaves romance, suspense, and early feminist urgency into a novel that feels strikingly modern despite its century of age. For readers who crave stories about women who refuse to wait to be saved.
