I would like to point out that the werewolves in my book aren't Twilight based (though there was a tongue in cheek reference...I don't think that Kirsty and her group would be among those that would closely follow the series by the time that would enter their timestream). David probably wouldn't be too pleased to be compared to those. David is actually a character created by my dear heart. That is why he's a werewolf. I don't think he's a fan of Twilight either.
However there is another reason that Kirsty is so drawn to David. This has to do with the divergence in hunters between the sea and the land. The book series is dealing with more than one theme and each deity has their own things that the two must navigate. I am looking forward to getting the books to the point where that is addressed more fully. I could have changed things to go with bears...but in my opinion wolves are sleeker and closer to the energies of Mara's children. Although Mara would want to reestablish closer ties with all land based hunters, wolves would be among her most favorite, especially with Herne having chosen them as his closest.
I still expect the full storyline to cover three or four books, each divided into sections of three (and there is a numerological reason for that)
