Told in text messages, this is the story of middle-schooler Ava, who's having a really bad day: her parents are getting divorced, she's had a big argument with her best friends, and the charge on her cellphone is getting low. But things are about to get a lot worse because the lockdown alarm has just gone off, and there's an intruder in the school building.
