My book was about a boy named Doug and his sister Colette. They live in a house in the woods. They go out and find a trapdoor where the Beasties live. They have to help the Beasties destroy the logging sites killing the forest where the Beasties live. One thing interesting about the book is the big hairy creatures called the Beasties.
I liked the book because I thought that the big tunnels where the Beasties live underground were cool. I didn't like that they didn't tell me if the Loggers killed all the Beasties or not. This was a very good book. I highly recommend this book to people who like science fiction.
