The second book in the W-3 Crew, Kevin M. Kraft takes our three unlikely teenage friends from the jaws of a sea serpent (in the first book) to the excited (*ahem*) bowels of the hollow earth, when Michael, Tanya and Justin encounter two young denizens from a subterranean city threatened by a greedy business man who plans toe exploit the heretofore unknown culture to the world on the surface for personal gain. In this book, Michael finds romance and the team meets a brand new character named Shan McCool who wants to join them in their quest for paranormal adventure. Considered "even better" than the first W-3 Crew novel, this story will captivate readers of all ages.
