I read "The Boys Start the War" by Phyllis Reynolds Naylor. It was great. It's about three girls 5that move next door to four boys. The boys miss their friends that lived next door so they put dead things in the stream separating their houses. The girls decided to get even by pretending one of the sisters was dead. Wally, one of the boys, declared war. Then they all played tricks on each other. The worst character because he always wished he didn't do the things he did.
