Larry Correia writes such badass stuff, and Earl Harbinger is the Alpha-male of the badasses. I absolutely loved the first two books. I have pre-ordered Monster Hunter Alpha. If you like witty dialogue, accurate shooty goodness, and killer story lines, you will love this series. You should go get a copy too.
Even though Larry says he will write nice things about me, I endorse these books because they are flat-out awesome. Go get you some.
(I received nothing of value for this rave-The FTC can suck it...)
