Did you think cockroaches could be good guys? Well in this book they are. Gregor falls through a grating in the floor to a place called the Underland. He doesn’t want to be there, but he cant get out. He tries to sneak away, but he runs into a couple of rats. They try to kill him, but the Underlanders save him and retrieve him. Vikus tells Gregor ‘The Prophecy of Gray’, and Gregor doesn’t get it, but it includes him. All of a sudden, one of the Underlanders comes in and proclaims to all of the Underlanders and Gregor that the rats are going into battle against them – the cockroaches, bats, and underlanders against the mighty and brave rats. Will Gregor die and not return to earth, or will he defeat the rats and live up to the prophecy?
