In this second book of The Jumper Chronicles, twelve-year-old Charlie and his mates discover an ancient compass that stubbornly refuses to point north. Instead, it steers them down a treacherous tunnel, each step taking them deeper into a world of dog-eating trolls, cross-dressing gods, and motorcycle-riding dwarves. As a cloak of darkness threatens to envelop the fellowship, Charlie loses his best friend, discovers true love, and is embraced by unexpected allies who guide him to a long-forgotten treasure that will change the world forever.
