Agatha Heterodyne returns to her ancestral home, the warped little town of Mechanicsburg, to convince the artificial intelligence that animates her family’s castle that she is, in fact, the new Heterodyne. But things get complicated when an imposter claiming to be the legitimate heir appears. Not to mention that the Empire is convinced that Agatha is the person responsible for the Long War. And, worst of all, the Castle itself is insane.
