Only Human (Sequal to Monster)
(This book takes place after the events of Monster.)
Everything seems right with the world again. Mitch has been accepted back into the rank of TC, The Pack has settled down in northern Minecraftia, and Dark has been banished to the Medium. But it seems that the Team has forgotten what started their trouble in the first place! The squids are back to their old tricks, now backed by an enemy far worse than Dark. With some new allies, and some old ones, the Team and the Pack have to take down this new menice, before the entirty of Minecraftia falls.
