But Stephanie sees transparent, gray arms reaching inside people's heads. Vaughn's vision of a blackness blowing people up from the inside out leaves him wondering. What is a faithwalker? Potentially, the most powerful person alive. Earth's only hope against the coming evils. That is, if they survive the terrible hardships into which they are always born. Call of the Tree is a fiery mixture of teenage passion for love, truth, understanding, and a deeply felt desire to see past the horrible world that adults have created.
