Ancient trolls have woken up and are living under suburbia! When Colin Colbeck's grandmother goes missing, it's up to him to find her. Followed by a reckless little brother and his ex-best friend, Colin stumbles into an ancient city of trolls trying to catch up to the 21st century. But old grudges die hard and an out-of-date troll war is about to pick up where it left off two hundred years ago. It's a contest of brains against brawn in this perilous adventure of friendship, courage, and bringing home the ones you love.
