I think Cindi J's review is quite comprehensive. What she doesn't say (and very likely didn't mind) is that this is in Regency-speak - not the slang, per se, but the obsessive politeness. Everyone uses a LOT of double negatives and such to work around giving insult. This is done to such a degree that it makes the reading slow going (at least for me it did).
Fun magic, fun villainy, fun characters but, oh, if only they could get to the point a bit faster.
