Author Alma Katsu draws from folklore and mythology to craft a haunting tale that asks, "Have you ever loved someone so much that you'd do anything for them?" Dr. Luke Findley arrives at his Maine hospital expecting another unremarkable day. Instead, he meets Lanore McIlvrae, who is brought in under arrest for murder. As Luke treats Lanore, she shares the secret of her immortality and reveals the love that has possessed her for centuries. It is a love that has been brutal at times, yet Lanore has remained true—until now.
