Yesterday I finished reading an anthology of short zombie stories featuring some LGBT aspect, "Zombiality: A Queer Bent of Zombie Fiction." Overall it was okay, but frankly, a lot of the stories sounded like they came from a creative writing class.
That said, one of them was terrific - "Sweetness" by B.C. Edwards. A great little story about a couple, one who has been infected with a virus that causes the person to become basically undead. It starts with a sweetness in the back of the throat, that eventually sends the person into madness. The story did a particularly good job about showing the difficulty of an infected person dealing with his fate, and the strain on his relationship (his boyfriend starts running with a group of zombie killers).
The best thing about this was its explanation of why zombies become flesh-eaters. It was a nice twist, and really well done. Worth checking out.
