Well Musicman88, it's different, I'll give it that. In saying that, it has the feeling that it could have happened, and makes a nice change to all those other stories that go along the same lines.
I honestly would have thought that Tobias, with all his time spent as a bird of prey, and as an Animorph, but, after all, you are the author so you have total control.
As for the whole Rachel+Marco thing at the end, personally I'm not a big fan of it, but it would be quite foreseeable, as opposed to those stories that just have Rachel committing suicide, or something equally as stupid.
Anyway, I think that this just another great story from you, and I'm still looking forward to some more of your more. . . adult stories.
