In the second volume of this trilogy, we get out of Spence Academy and into the streets (well, the wealthy houses) of Victorian London. Gemma and her friends have a task before them: re-bind the magic Gemma accidentally loosed before Circe can bind it for herself. 
 Rebel Angels hits the supernatural elements harder than the first volume--this one is more a fantasy with historical elements than the other way around. Still, it's good, and I'll be starting the third volume once I catch up on some of my audio backlog. (The reader for this, Josephine Baily I think, is very good, and I'm happy to stick with her through the end of the series.)
