I really don't know how to feel about this one. On one hand, it's an interesting take on magic as a social art in regency society. The heroine is intelligent and deserves a medal for putting up with her family. Though the voice is nowhere near Jane Austen's, this would seem to be what the regency era would have been like with magic involved.
The last parts were quite riveting, but until you get there it feels awfully plodding. The chapters just keep heaping misery upon misery on our poor self-sacrificing heroine, and that can get tiresome after a while. The love interest suffers as well, but more from a lack of real characterization than anything. When I finished the book, I thought that while their connection is actually romantic, they wouldn't be able to stand each other in time. Their connection definitely needed more work.
Man, this is hard to discuss without resorting to spoilers.
