After joining forces with the magical Nightsiders and surviving a trip to the enemy Bugs Hive ship, Milo Silk still has a lot to fear. The Huntsman has pledged a revenge worse than death on Milo, a group of nefarious fairies are bent on taking back Earth, and zombie-like holo-men are trapping humans for the Bugs to take. Even more unsettling is that the Witch of the World has disappeared and a mysterious boy is haunting Milo s dreams in her stead. But none of these threats compare to what may happen to the world if the humans and the Nightsiders don t unite to fight for each other.
