Showing Probability Angels by Joseph Devon

Matthew knows that he died twenty years ago. He has, after all, been bouncing around New York city ever since, causing mischief and having fun as a supernatural being. But recently some problems have been cropping up: not only is he hallucinating things in garbage cans, but his mentor doesn’t think he’s working up to his full potential, his best friend can’t offer any solace but drunken confusion, and his wife is dying in Central Park.
See, the past twenty years haven’t meant a thing because now it’s time for Matthew to make his second choice and become a tester of humanity.
And that’s all before the zombies show up.
Come explore the world of Matthew and Epp and see what a samurai from Feudal Japan has to do with the course of modern physics, what a two-thousand year old Roman slave has to do with the summit of Mount Everest, and what a dead man from Brooklyn has to do with the fate of the world.
