When Michael’s mother dies he is startled to see her ghost at her own funeral. When he sees her again just as a dark shadow engulfs her he realises that something is wrong. His grandmother explains that the Spirit Tree that stands in the forest has the power to cleanse all souls before they go on to Heaven but it has become tainted somehow. This taint has affected all the forest guardians and the other fairy folk making the woods a very dangerous place to be in. But more unsettling is that souls are now unable to get to Heaven and wander the forest.
Determined to save his mother’s soul Michael and his friend James enter the tainted forest where they soon meet one of the forest guardians. Billy Blin looks the same age as the human boys and has managed to remain untouched by the taint. He promises to help them reach the Tree as this will also help his own people to return to normal.
They follow Billy as he guides them through the forest while they are pursued by the King's Huntsmen and the Queen's Court determined to stop them. Even the very trees are against them!
