Cold Case of the Witch — Judith Berens

It can be tough to get an education at the School of Necessary Magic. Good thing Raine Campbell is a witch who longs to be an FBI agent. That's a girl with a dream―if she can live through her school days. When Raine finds hidden messages and symbols in old yearbooks, it can't be ignored. Not if she wants everyone at school to stay alive. Some investigations need the help of trusted friends. Time to ask for help―it's going to take everyone in her circle of magical friends to solve this mystery. Join Raine and her friends as they solve dangerous puzzles and go where the evidence leads them.
