Twins Jacqueline and Darwin Ellery have just been expelled from the third boarding school in a row. As their father debates sending them to separate schools, if there are any left in the Drevian Federation willing to accept them, a letter arrives from the twins’ estranged—and strange—cousin Benedict Rook, Wellsverne University’s youngest professor ever and an investigator of the paranormal. Benedict takes them under his wing, although the twins soon learn that life under his tutelage is anything but ordinary. Jac and Darwin get drawn into Benedict’s obsession: finding his mentor Anton DeVol, former head of a multibillion dollar robotics company, who vanished five years ago.
