Gregor the Overlander is a story about an 11 year old boy named Gregor that wanted to find his father who has been missing for two years. Thinking about his dad, he falls into a underground world. Here he goes on a quest to find his father, will he succeed? Can he possible survive the giant creatures and other dangers of the Underland?This book is recommended for readers who like action, and are not bothered by violence. This book is also good because it is full of surprising events and cliff hangers that will make you want to read more. You will not be able to put it down.This book is not recommended for those who do not like fantasy stories. We think this story is best for grades four and up. The way the Underlanders speak can make the story a little difficult to follow.In all we really loved this story and are looking forward to reading other books in the series.
