Zero History(2010)

William Gibson

Hollis Henry never intended to work for global marketing magnate Hubertus Bigend again. But now she’s broke, and Bigend has just the thing to get her back in the game...

They all have something Bigend wants as he finds himself outmaneuvered and adrift, after a Department of Defense contract for combat-wear turns out to be the gateway drug for arms dealers so shadowy they can out-Bigend Bigend himself
