It's the new full-length book. The novellite (Micah-style) was something different, but she said that now she wasn't sure she'd be able to finish that one.

From her blog again:

Feeling some better today. I've never had a book get to ninety pages then just stop, and tell me this isn't working. I think the plot will get used down the road, but there's something about the weretiger stuff that needs to be touched upon in the next as yet unnamed Anita novel. I've learned not to argue with my subconscious, I usually regret it later. But it still feels like wasted effort. I now have an almost equal page count for both books, how weird is that?

So, they are two separate books, both including Edward though.
