Lioness of the Lowlands

"Yesterday, in a case of mistaken identity, a demon murdered Salem's best friend. Today, that demon will try to kill her. Tomorrow, she intends to return the favor. Transported to a place where the demon reigns, Salem must fight for her life and the lives of her friends. Chosen fifty generations before her birth, Salem can hardly grasp the fate that demands she confront evil incarnate face-to-face. If she survives the battle, the demon's power will be destroyed and the enchantment concealing her way home will be broken. If Salem wins, she doesn't know how to return to the man she's grown to love."
