Working at the local processing plant, Marcos is in the business of slaughtering humans —though no one calls them that anymore. His wife has left him, his father is sinking into dementia, and Marcos tries not to think too hard about how he makes a living. After all, it happened so quickly. First, it was reported that an infectious virus has made all animal meat poisonous to humans. Then governments initiated the “Transition.” Now, eating human meat—“special meat”—is legal. Marcos tries to stick to numbers, consignments, processing. Then one day he’s given a gift: a live specimen of the finest quality. Though he’s aware that any form of personal contact is forbidden on pain of death, little by little he starts to treat her like a human being. And soon, he becomes tortured by what has been lost—and what might still be saved.

Why do Roman numerals persist? How do we know that some infinities are larger than others? And how can we know for certain a program will ever finish? In this fast-paced tour of modern and not-so-modern math, computer scientist Mark Chu-Carroll explores some of the greatest breakthroughs and disappointments of more than two thousand years of mathematical thought. There is joy and beauty in mathematics, and in more than two dozen essays drawn from his popular “Good Math” blog, you’ll find concepts, proofs, and examples that are often surprising, counterintuitive, or just plain weird. Mark begins his journey with the basics of numbers, with an entertaining trip through the integers and the natural, rational, irrational, and transcendental numbers. The voyage continues with a look at some of the oddest numbers in mathematics, including zero, the golden ratio, imaginary numbers, Roman numerals, and Egyptian and continuing fractions. After a deep dive into modern logic, including an introduction to linear logic and the logic-savvy Prolog language, the trip concludes with a tour of modern set theory and the advances and paradoxes of modern mechanical computing. If your high school or college math courses left you grasping for the inner meaning behind the numbers, Mark’s book will both entertain and enlighten you.

The apocalypse will be televised! A man. His ex-girlfriend's cat. A sadistic game show unlike anything in the universe: a dungeon crawl where survival depends on killing your prey in the most entertaining way possible. In a flash, every human-erected construction on Earth—from Buckingham Palace to the tiniest of sheds—collapses in a heap, sinking into the ground. The buildings and all the people inside have all been atomized and transformed into the dungeon: an 18-level labyrinth filled with traps, monsters, and loot. A dungeon so enormous, it circles the entire globe. Only a few dare venture inside. But once you're in, you can't get out. And what's worse, each level has a time limit. You have but days to find a staircase to the next level down, or it's game over. In this game, it's not about your strength or your dexterity. It's about your followers, your views. Your clout. It's about building an audience and killing those goblins with style. You can't just survive here. You gotta survive big. You gotta fight with vigor, with excitement. You gotta make them stand up and cheer. And if you do have that "it" factor, you may just find yourself with a following. That's the only way to truly survive in this game—with the help of the loot boxes dropped upon you by the generous benefactors watching from across the galaxy. They call it Dungeon Crawler World. But for Carl, it's anything but a game.
