Query: Holes Review

I liked Holes a lot. It had many ups and downs. Some of the ups were towards the end of the book. Some of the downs were that many characters like Barf Bag and Twitch were not used much. I liked the way Sachar named the main character. The other characters also had funny nicknames. My favorite line was "no-good-dirty-rotten-pig-stealing-great-great-grandfather".
