It lurks in the shadows. It lives in your worst nightmares. It feeds on your deepest fears. It's the Master Trickster, and it's coming to get you. When she loses her parents in an accident, Diya Mathur's world collapses around her. As far as she knows, she's alone in the world now - till a mysterious letter arrives from India. Suddenly, Diya has a chance at being part of a family again. But moving from Boston to India also brings Diya closer to the place where the horror of the Chakwa - the Master Trickster - first started. As bodies and tragedies pile up around her, Diya's belief in the urban myth of the Chakwa increases. Will the monster that ruined her parents' life now destroy Diya's happiness? Or will she manage to defeat him at his own game? With the help of her newly discovered friends and family, Diya must fight not just the monster from her nightmares, but also make sense of a fast-unravelling web of lies that makes up her life.
