Diary of a Zombie

Tom was living a normal life. He had a girlfriend that would soon move in with him, a group of loyal friends that played boardgames with him, and a good job that he didn't hate and paid well. Nothing lasts forever, though, especially good things. One day, he died changing a light bulb. And then, he got up again. What will he do, being the world's first zombie? How will he keep himself hidden? And how will he manage the fact that he can see dead people?
