Review: Inside a mountain, the steampunk city of Cove has very strict laws against creativity and the word “invention” is a curse word. Thirteen-year-old Trenton is creative, inquisitive, and loves all things mechanical – to his peril. He and Kallista, the daughter of the criminal inventor, Leo Babbage, are on a mission to resolve the power outage that has been blamed on Trenton. They must use illegally created blueprints left by Babbage while evading the government. Friendship and family issues interweave with survival instinct under oppression as the two combine efforts only to find they just might be threatening the underpinnings of their city and endangering their own lives.
