Zero history - William Gibson

Former rock singer Hollis Henry has lost a lot of money in the crash, which means she can't turn down the offer of a job from Hubertus Bigend, sinister Belgian proprietor of mysterious ad agency Blue Ant. Milgrim is working for Bigend too. Bigend admires the ex-addict's linguistic skills and street knowledge so much that he's even paid for his costly rehab. So together Hollis and Milgrim are at the front line of Bigend's attempts to get a slice of the military budget, and they gradually realize he has some very dangerous competitors. Which is not a great thought when you don't much trust your boss either.
Gibson's new novel, set largely in London, spookily captures the paranoia and fear of our post-Crash times.
