I really liked this book. It was imaginative, icky, heartwarming, funny, and very difficult to review without giving too much away. There are battles and friendships with underground humans, rats, spiders, and cockroaches, which Gregor must handle while protecting his two year old sister and looking for his long-lost father.

Gregor the Overlander is a great portrayal of a compassionate, struggling, frustrated, scared kid, who has had to deal with real hardship in his life. But when things suddenly get weirdly worse, Gregor rises to the occasion.
