I have to say, this isn't really among my favorites of in-progress serials. Still, I do enjoy all four of the books and read this last one without ever getting bored. Even with Cormac playing a more minimal role than usual, stuck up in prison as he is. Which, by the way, is sad because Ben does absolutely nothing for me. There's just no magic. Which, I believe, may be just a little bit intentional. Read the last two pages and you'll pick up on why I say so. Ah, screw this subtlety bit -- Ben ain't the long-haul guy. I don't peg him for getting killed off just yet (though I'm hopeful) but I sense no HEA here.
BTW: African wild dog... whoddathunkit?
