This is a wonderful book about crafty little people. They were a size of the thumb and had a tail. Rats were attacking them. Littles used little knifes that they made to fight them. Mr. Big always wondered why his phone system was working so well. He did not know that the Littles were living in his house. The Littles fixed the phone system. The Biggs went away for vacation for the summer and Newcomes rented the house. The Newcomes were very messy. Rats came into the house. Tom Little decided to play a trick on Newcomes and dressed as a rat. He wanted them to set mouse traps. But the Newcomes decided to bring in a cat. The Littles were very scared and they wanted to get rid of the cat. But Tom became friends with the cat. I loved the book because the Littles were always solving their problems. I would recommend this book to my friends. I will read other books by John Peterson.
