Twelve-year-old Andora ‘Andi’ Boggs and her new best friend Colin Carter couldn’t be more excited to attend the prestigious science camp at the local university in Killdeer, Ohio. Unfortunately, Discovery Camp’s curriculum appears to include much more than just chemistry and biology.

From day one, the university is plagued by a series of pranks—missing markers, loose crickets, and stolen scales. Campus security blames the mysterious janitor Polk, but even though Andi agrees he’s acting suspicious, she can’t believe the gentle old man would do anything illegal.

Then one prank goes too far and their chemistry professor is injured by an explosion in the lab, upping the stakes of the investigation. Andi and Colin must unravel the secrets behind the chemistry department and Polk’s dark past before danger closes the camp for good.
