Publisher's Synopsis
Evil and danger rumbles under the earth. Follow the adventures of a group of contemporary teenagers who discover that their town, and ultimately the entire world, is under attack by fierce creatures from deep beneath the earth. These creatures were known to the earliest humans as trolls or goblins, but they are much more dangerous than their fairy-tale versions. The teens make unlikely allies along the way, including a half-man, half-troll, as well as some legendary constellations that quite literally come to life. The young heroes will also discover their own untapped celestial abilities in an epic battle between good versus evil spanning four intense books.
