Twelve year old Jack and his cousin Katie are snatched by Hero, a grumpy leprechaun, shrunk and whisked off to the magical kingdom of Kindling on a mission to save it from fierce invaders called Gangrals. On their journey they discover extraordinary creatures; some friendly, some hostile. Stranger still, the cousins have been there before in another lifetime and are hailed as returning heroes, but Jack has no recollection of this. Now, as the kingdom’s last hope, they are expected to fight the invaders and outwit a dangerous traitor with a deep-seated grudge against the queen. Can Jack and Katie do what is expected of them or will the kingdom fall?
