After stealing a powerful book—said to house the soul of the ancient witch Morgana—Hanna Lyons is tasked with the capture of the very man she took it from. In a race against time, she must discover the identity of the elusive Pied Piper, and find a way to destroy the book before catastrophe unfolds.

As Hanna grapples with her inner demons, and discovers the truth of her own identity, she must learn to accept that sometimes the lines between good and evil aren't always as black and white as they seem.
