Isabel can't believe what's happening to her... the IM gossip chain has gotten way out of control, and she's the target. Mean messages and whispering classmates are popping up in the strangest places -- including a certain Queen of Mean's away message. How did things get so out of control? Everybody says they're "just kidding," but it's not funny at all. Someone is poisoning Spirit Week with her twisted lies. Drama overload! To top it off, Miss Pierce has mysteriously disappeared, and Charlotte is petrified that her friend is gone for good.
