In modern day Britain, society lives in fear of Leeches: creatures that look exactly like humans, yet hunger insatiably for blood. The world is divided- Leech or Human. A war is brewing and at the center of the conflict lies Mara Wilcox. Mara a bookish and ordinary young woman, is restless in her search for her siblings. In a twist of fate she finds herself face to face with a 'vegetarian' leech; Kit Hunter. Their chance encounter leads to a chain of events that will forever alter the course of their lives. As truths are revealed and lies uncovered, Mara and Kit learn that the only way to survive is to trust one another. "It's scary how everything you're saying to me could be a lie..." His lips were on her pulse under her jaw, pressing a slow trail of kisses down the pale stretch of her neck. "I promise you can trust me. You're worth being good for."
