AMC have released the first four minutes of the first episode of the new Walking Dead half-season (that's a mouthful) which airs on Sunday. I haven't watched it myself because the flipping content isn't available in my country. Hate it when they do that. But if you're in the US you can watch it, and if you're in the UK, you can read Bloody Disgusting's review of the clip here.
And on the topic of zombies, my own zombie podcast novella, After the Plague, will soon be available to download from my page at Podiobooks. Watch this space for updates!
