About This Book

The rumble of the miners' train shakes the air, dust swirling around the cramped car as it hurtles deeper underground. Will, Chester, and Cal grip their seats, hearts pounding, as they descend into a shadowy world where danger lurks in every tunnel. Beneath the surface, a deadly secret threatens everyone above, and the boys must face it together.
