At first, I really, really wanted to slap Abigail, especially after her description of Miss Hawk and her everlasting obsession with the pom pom squad, but... it's a pitch perfect middle school voice, and she does learn a hard, hard lesson that so many middle school girls learn. Friends change. Popular people can be mean. Things that seem like a good idea at the time are not. Mistakes are made at very loud volumes, in front of everyone. Cavanaugh really knows her demographic, writes effectively and convincingly, and even the format (lists) works.
