Third in the Cal Leandros/Nightlife series by Rob Thurman...
First off, it is not nice to end a book on a cliff-hanger when the next book in the series isn't out yet! Not nice at all!
The basics... this crazy canibal monster has come back to life and the guys have to stop him. Meanwhile someone is trying to kill Robin for reasons unknown.
There's a lot of interesting internal stuff going on with Cal in this one. He's finally becoming attached to people other than his brother and he doesn't know how to deal with that, how to deal with caring for other people and worrying about them. And of course he's still trying to figure out what it means for him to be half-Auphe. Does using those abilities make him closer to them? Less human? Or is it just using what he has?
On a totally shallow note, I really want Niko to get his braid from the first book back. I know, hair takes a long time to get that long, but it was such a neat detail. I really liked it, and I miss it.
