As mentioned by lots of other reviewers, the first third of this book was really slow, with discussions of Allie's memory loss and it dragged so much for me, that I put the book down and read some other stuff first. Since I picked it up again, the story picked up speed and I really enjoyed it.
This is a complex, magical world, where nothing comes easy and every time someone uses magic, there is some kind of payback - headache, fever, coma, memory loss. My biggest problem with the memory loss, is not that Allie doesn't remember, but it sometimes seems like a convenient way for the author to get Allie out of a jam.
I also enjoyed Allie's growing relationships with everyone - her love interest, her stepmother, the other magic hounds, and her learning about the Authority, and what she may be learning from them. I'm looking forward to seeing how this all plays out in the next book.
