Chrestomanci Series Book One: Charmed Life. I'm only about five chapters in, and I must say, I'm quite enjoying Gwendolen's frustration. Little brat is far too used to getting her way. I pity her brother, though; looks like he's getting dragged through the muck with her.
Fingers crossed character development changes Gwendolen's attitude; otherwise it's going to grate on my nerves all the way through. Chrestomanci himself is just perfect. :laugh:
Edit: Finished it. Gwendolen's attitude remained the same--if not worse--but given the course of the story, it was fitting. At least her brother, Cat (Eric) developed nicely. I really want to read more of the series, now. ^^
