Minerva Keen is the absolute best kid detective Chicago has ever seen, and she’s hungry for a new mystery to solve with her friends.

Standing in her way is the know-it-all new girl, Zoe, who tries to take control of MK’s Detective Club. Worse still, the club adviser who has always had a soft spot for Minerva takes Zoe’s side, and that’s just the start of the strange decisions Ms. Voyant is suddenly making.

Add in terrifying nightmares, the return of Minerva’s parents, and shocking new developments — MK’s Detective Club just might have more mysteries than they can solve.

With nowhere to turn, the club walks right into danger.…Will they be able to find their way out?
