Pablo, Thora, Zak and Louise are regular teens living in an ordinary small town. When they discover their town, and ultimately the entire world, is under attack by fierce creatures from beneath the earth, the young heroes must join together in a fierce battle between good versus evil.

Evil and danger rumble under the earth. Follow the adventures of a group of contemporary teenagers as they fight against creatures known to the earliest humans as trolls or goblins, who 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 this intense, page-turning book.
