Monster Pizza Hunter, by Larry Correia
Due in Bookstores by September or it's FREE!
Owen Z. Pitt collapsed his bulk into the low slung couch and groaned. The sling buckle from Abomination dug into his already bruised ribs. The non-stop action of the past three days had earned him, and the rest of MHI, enough of a PUFF bonus that he was going to have to open another IRA, but if every bone in his body wasn't broken, or at least bruised, then it wasn't the fault of the swarm of cranky Cub Scouts that had lept out of the trees on him as he was disposing of the last zombie attack at Mickey Pearl's Fabulous Outdoor Petting Zoo. He leaned his head back, and let his exhaustion overcome him...
..."HELLO IN THERE! What are you doing?"
Z snapped his eyes open, to find himself sitting in a field being cropped by sheep. Leaning over him was the figure that had saved his life, and the world, despite being dead.
"Hello, Mordechai. What's wrong? I thought we got all the infestation cleared out?"
"Oh, so it's mister knows-it-all still, heh? You deal with a few undead, and you think you can just take your ease! Well, listen mister know it all, if you'll pay attention, you'll hear the sound of your wife in the kitchen, trying to fix something for you to eat, while you sit drooling on the couch. GET UP, bubie, and go help her! You're newly weds, remember? Or do you want to grow up to be EXACTLY like your father, a good man though he is?"
"No, you're right. " Z blinked his eyes again, and was back in the living room. With a groan and a grimace, he eased his way into the kitchen, to see Julie gazing into a nearly empty cupboard, with a frying pan in her hand.
"Look, honey, I'm about tired to death, and you worked as hard as I did, if not more. How about we just call out for pizza tonight?"
Julie turned. The light from the setting sun glistened off the tears forming in her eyes. She released her grip on the frying pan, and let it fall to the floor. In a moment she was in his arms, clutching his load bearing equipment, and whispering, " Z, you are the most thoughtful man on the planet."
Z thought "Man sometimes it's really good to have a crazy dead guy in your head," as he patted her back. He thought he heard a ghostly chuckle, but wasn't sure.
