Have you ever wondered what it’s like to live through a bioweapon attack or to have every aspect of your life governed by invisible ants? In Cory Doctorow’s collection of novellas, he wields his formidable experience in technology and computing to give us mind-bending sci-fi tales that explore the possibilities of information technology-and its various uses-run amok.

Anda’s Game is a spin on the bizarre new phenomenon of cyber sweatshops, in which people are paid very low wages to play online games all day in order to generate in-game wealth, which can be converted into actual money. Another tale tells of the heroic exploits of sysadmins-systems administrators-as they defend the cyberworld, and hence the world at large, from worms and bioweapons. And yes, there is a story about zombies too.
