Gregor the Overlander is a very good story. There are bats, rats, spiders, and many more types of characters. Suzanne Collins (the writer) did a very good job with this book. I recommend this book for sci-fi, fantasy, and adventure story lovers. There is so much excitement and suspense. You fall in love with the characters easily. Gregor and boots (his younger sister) fall down a hole in the laundry room. They land in the underland and Gregor has to face the fact he may never see his mom and other sister. He soon finds out his father (that went missing years ago) may be in the underland. He goes on a journey with a lot of battles and life’s lost.
