Fun collection about the Earth as run by demons who treat humans as second-class citizens. One teenage girl, Riley seeks to find answers to her past, as her exiled father left her with a half-pendant which might unlock the secret to human liberation. She's now on the run with her adoptive demon "priest" and giant robotic ogre, flying a church blimp to the wastelands. 

 

Sounds exciting, but apparently the sequel never materialized!
