Groove to new e-books by David Wellington.
I just read 32 Fangs. I really enjoyed it. He wrote the super-brilliant Monster Island too, which is the best zombie novel I've ever read.
Oh, and he wrote 13 Bullets and... it turns out I've read most of his books.
And Frostbite is very good.
Also I read his first self-published novel but I can't find it on Amazon.
