Exiguous [EPUB ebook] 

Preppers outnumber rich people in America 10:1. When SHTF, those with physical currency and possessions able to be readily converted to physical currency will survive the best. Guns and ammunition may prove to be useful in motivating someone to relinquish possessions, but Preppers are heavily networked and themselves well-armed. Most are off the grid, with solar power supplies with hundreds of batteries capable of operating for days without adequate sunlight. You should be terrified at what they are capable of orchestrating.
