Found this one a little odd to start with. I expected a fantasy novel and got. . .Jane Austen with fantasy elements. I spent the first third of the book just trying to figure out what the heck I was reading. . .the second third caught up in the gothic mystery, and settled back to enjoy the final third.
Despite all that, by the time I was done I can say I really did enjoy the book. It was definitely Jane Austen-ish, with a whole gothic mystery smack in the middle of it (compelte with creepy children!), before it returned to Jane Austen. And in the end, the fantasy elements came together.
The only thing I really didn't care for was the odd day/night cycle (lumbrals and umbrals) which were never really explained and just sort of . . .weird.
