The novelization of the first two Agatha Heterodyne graphic novels.
A faithful retelling. Those who don't want to read the graphic novels will get the story as the Foglios told it. Those who have can get some additional insights, because the medium, naturally, gives them more scope to get inside people's heads as we go through the story of how the Baron came to town, and Agatha discovered who is she is.
In particular, there are some insights into Moloch's behavior that make his later changes more coherent.
