I read this one pretty quickly and enjoyed it.
Rose volunteers at her daughter's school to be a lunch mom because she wants to see what's going on. Her daughter, Melly, is being bullied because she has a red birthmark on her face. While at school, Rose sees her daughter's chief tormentor take some jelly and smear it on her own face to make it look like Melly's. Melly see it and runs into the handicapped bathroom.
Just then there is an explosion from the kitchen. When Rose regains consciousness, she has to make a horrible choice: run to the handicapped bathroom to save her daughter or try to get the bulliers out safely.
Her decision results in a maelstrom of condemnation from the parents and townspeople. But something seems fishy to Rose about the explosion so she embarks on a quest to find out what was really behind it.
Nonstop action, likeable characters, a believable solution all add up to a great read.
