Listen to Scott Sigler. He writes some of the best stuff out there now. And he is very approachable/ available with a big online presence. He started out inventing the Podcast Only novel, but now he has books in print with a new one (Contagious) coming out December 30th. All of his stuff is really fast paced, gripping, violent, and pretty frickin awesome. You can get the podcasts for free on his site, but you should buy his books too. I have reviews of his stuff in other posts but I recommend you just read/ listen to them.
