The idea I've always had for a zombie story is actually the only one in which there is a cure for zombification. The thing is, zombies rot and fall apart with time, which means that if and when they get cured, they don't just regenerate, they come back as disfigured people with zero memories of the time they were zombies, as well as the added stigma of probably having killed and eaten somebody while zombified.

So the whole shtick is how do you reintegrate into society as a former zombie, scarred and treated like a monster, even though you're just supposed to be a normal dude again? I'm not mature, insightful or wise enough to do that premise justice, but I think it would be real neat in the hands of someone who's a better writer than I am.
