This irresistible first novel tells the story of a quiet boy who embarks on a dangerous quest in order to fulfill his destiny -- and find his father -- in a strange world beneath New York City.

When Gregor falls through a grate in the laundry room of his apartment building, he hurtles into the dark Underland, where spiders, rats, cockroaches coexist uneasily with humans. This world is on the brink of war, and Gregor's arrival is no accident. A prophecy foretells that Gregor has a role to play in the Underland's uncertain future. Gregor wants no part of it -- until he realizes it's the only way to solve the mystery of his father's disappearance. Reluctantly, Gregor embarks on a dangerous adventure that will change both him and the Underland forever.

          The series was really cool! Imagine a world where all your everyday creatures are oversized. That is what the UNDERWORLD is like in Gregor's land. He must venture out into the world and save Regalia, which is like Rome but a lot more modern, and dark. Collins wrote a book nothing like the hunger games, and I think all of the Collins fans out there should read it!

              I read this book a while back and it was so great, I read the whole series. It is about a boy named Gregor who one day accidentally falls in a hole and discovers the underland. He realizes he is the warrior of the prophecy of gray and goes on a journey to save someone and fufill the prophecy along with his sister Boots(nickname).

                    I loved this book so much! It has a lot of action in it. The action is fast and exciting. There are five books in the series, and I recommend them all.

                      I read this book for a school project. I had to think of a way to end my project without spoiling the book. The endings of the chapters got better and better so it was hard to decide. This book was an amazing book and I hope to read the rest of the series!
