Gregor and the Great Return

The underland is in grave danger. Gregor has lived a normal life in the overland for only three years and is striving to forget his past when he gets a strange message. The message is frantic and urgent telling him that they need the warrior and that many will die if he doesn't come. So will Gregor sneaks out and down the grate in the laundry room? Or will stay above where his family wants him. Find out with chapter 1. I don't own any of the characters. Suzanne Collins does :)
