Witches are creating havoc in the Wildwoods and danger lurks behind every tree trunk. Wish is in possession of a powerful, Magic Spelling Book. Xar has a dangerous Witchstain on his hand.
Wish and Xar are separated by the highest wall imaginable. But time is running out ...
It was unlikely that these heroes should meet in the first place. Is it possible they are destined to meet TWICE?
