Infinite Zombie Coins: Buying Out the Apocalypse

Fred Lane had seventy thousand coins saved and a girlfriend who asked for all of it as a wedding gift. He handed it over. Soon after he learned she had been sleeping with another man for a long time, and by then the apocalypse had already begun, with monstrous things spreading across every city and the old currency worthless beside the coins scavenged from the dead. Broke and dumped in the same week, Fred found that something had switched on inside him: an account with an unlimited balance, on one condition. Whatever sum he is holding must be spent within twenty-four hours or he dies, and every hour the balance doubles on top of what he failed to burn through. So he goes shopping in a ruined world, buying weapons, buildings, protection, and people's loyalty faster than the total can climb, and the spending itself turns him into one of the powers of the new order. His ex, who counted seventy thousand as a fortune worth lying for, keeps running into him at the places where the money now decides who eats and who is fed to the things outside. The richer he gets, the tighter the clock on him pulls.
