Excellent work. Quite unique. What I find very interesting is the way Blake's new school friends seem to defer to him as the leader, even though they are quite powerful beings in their own right. I'm getting the feeling that while wizards and witches tend to build their power structure based more on wealth and political power, magical beings seem to be far more in tune with magical power and potential power. Which would explain why Ryan, amoung others, wasn't demonstrating his Alpha status - he subconsciously (or consciously) recognized a superior Alpha. Physical size isn't the determining factor, as Ryan demonstarted by assuming Alpha over larger werewolves.
I'm getting a feeling of similarity here between Harry/Blake and Anita Blake. Both starting out small, both developing more power/powers as they progress, and both getting the respect/reverence from the community of magical beings (and technically being one themselves). I also see Ryan as more of a Anita Blake style were, than a JKR. Then there is the similarity in names, Blake. Is this all coincidence, or a tip of the hat to a writer you respect?
