I've got to say though, I did like the element of mortality in the story. It gave a weight to things. There was a poignancy in knowing that, while some characters might live a significant time, others were going to live shorter lives- either through accident or inevitable old age. The ability to remove wolf blood eliminates that and makes it a choice.. and there is something a little lost there- I dunno, some feeling about it that I don't quite know how to explain. I guess, before it was bittersweet- and now it's just.. a magical solution you either choose or not?
