Choose Your Own Adventure books–the 4th bestselling children’s series of all time–are back and as much fun as you remember. Kids and adults agree, these are the books that get 9- to 12-year-olds reading.

YOU are a successful young detective, and the creepy Marsden residence and its missing owner have haunted you more than any other case. Maybe this is a sign you shouldn’t continue? Do you call in your best friends for support? Or perhaps you should turn to the police for help? Are you ready to take on mutant chimpanzees, time travel, and a counterfeiting ring to solve the case? Be careful, the choices YOU make might end in glory, disaster, or certain death.
