"A young girl missing in Fair Rock, Michigan!" The local headline is just what seventh-grader Alexus Harris has been waiting for. She's read every Detective Ginger book, investigated every major crime across the internet, and roped four friends into joining her crime-solving club. Now they have an actual crime in their own community.

The young detectives waste no time working the case and tracking down leads...but hit a roadblock when they discover two more girls are missing. The crime-busters realize they need backup.

The girls hunt down a mythical sorcerer rumored to give superpowers to those clever enough to find him. He grants their wishes, but they don't get exactly what they're expecting. Now each girl must quickly learn how to control her new superpower before the missing children disappear forever.
