Holes by Louis Sachar -- 272
So here at Camp Green Lake Stanley is digging holes and told to report anything interesting. Soon he begins to realize that they are not digging holes just to build character, but that the administrator is looking for something, something she will do anything to have, and it just might have to do with the outlaw Kissing Kate Barlow. Stanley is ready to solve the mystery.
Holes is an exciting and suspenseful book, as well as funny. The writing style is gripping and doesn't drag at all, so it makes for a good juvenile fiction book.
