Lisa Burgess I read this one first. Took longer to get attached to it, but I will go back now and read the first. In my opinion it could very well be a standalone book.
Carry As far as I know, you need to read The Wolf Gift first. I bought this book first, and I noticed that there is a summary of the previous book in it, so you might be able to read this alone. But I am reading The Wolf Gift first (I'm now 100 pages in)
Sally Crawford I believe it could be a stand alone ;book and why not read the trilogy I love Anne Rice's writing and had to go to the next one.
