Higher Learning — Clare Kauter

Charlie Davies is about to face her worst nightmare: she's going back to high school. Following the death of a local schoolgirl, Charlie must go undercover to find out who is dealing drugs to students. Not only does this mean heading back to class, but she must also get to know the girl's friends - who happen to be cheerleaders. Time to break out the pom-poms. While at school, Charlie runs into her ex-boyfriend, now a science teacher, and can't tell if he's just being friendly or if there's something a little off about him. And naturally, police officer James McKenzie is working the case too - which is kind of awkward, seeing as he and Charlie haven't really spoken since The Incident. None of this adds up to a fun case. That's some maths even Charlie can do.
