"Clem gets a call that is every mother's worst nightmare. Her nineteen-year-old daughter Erin is unconscious in the hospital after a hiking trip on the Orkney Islands that met a horrifying end. Even worse, her boyfriend is dead and her best friend is missing. When Erin wakes, she doesn't recognize her mother. And she doesn't answer to her name, but insists she is someone named Nyx. Clem travels the site of her daughter's accident, determined to find out what happened to her. But instead of answers, she finds a dark secret in the history of the Orkneys: a woman wrongly put to death for witchcraft four centuries ago and whispers of a hex she set in retaliation. Clem begins to wonder if Erin's strange behavior is a symptom of a broken mind, or the effects of an ancient curse?" -- Provided by publisher.
