Following Jamie's spate of disrecommendations, Misha Glenny's Dark Market is crap. I liked McMafia a lot, and his book on the Balkans, but it's abundantly clear from the start that Glenny doesn't know anything about computers or geek culture, and will swallow pretty much anything he's told. It reads like an Internet panic story from 2000 or so, and it's strangely clumsily written to boot. The only thing I got from it was finding out, in passing, about the 1996 Turkish car crash involving a Parliamentary deputy, the chief of the Istanbul chief, and a heroin smuggler and contract killer. Rather disappointed by The Anatomy of a Moment, about the failed Spanish coup, as well.
On the positive side, Martin Gidron's The Severed Wing is one of the few Holocaust novels worth reading. (Terrible, terrible cover, though.) It's an alternate history with a swift Great War and no Holocaust, about a world with sixteen million Jews, abundant Yiddishkeit, Polish pogroms, and all that was lost, both in reality and in potential. It's frequently a little too smart with the alternate references - Bill Gates as a windows salesman, for instance - but it's clever and sad and sometimes beautiful.
