A New Zombie trilogy to read

I picked up a a few new books at my local book store recently called Zombie Island and Zombie Nation by David Wellington. I admit I am a fiend for anything Zombie and loved Brian Keene's The Rising and City of the Dead. I have finished Zombie Island and am well into Zombie Nation  and they are both really good stories with great characters. Zombie Island tells the story of a UN wepons insector that get's charged with the mission of finding critical medicine needed by a Somalian warlord that has his daughter under her protection. After searching the world he knows of only one place to find what he needs,the UN building in New York and the only thing between him and completing his mission are half the world and millions of the undead. Monster Nation goes back to when the first outbreak happens, and will be followed in the future by Monster Planet. Now, if you want you can go to the authors website www.davidwellington.net and read them for free or send them to your phone or PDA or I-Pod but getting them in print is better because the author has added chapters and you support the author as well. I am an avid reader of horror and I highly recommend this series of books.
