In reply to planetmarshall:
> The Looming Tower by Lawrence Wright
Very good and, being written by a New Yorker journalist, an easy read.
> Osama bin Laden by Michael Scheuer
Scheuer has his own very specific and now really rather odd views, just worth keeping in mind, but because of his job could perhaps claim to have learnt more about Bin Laden than most others in the west.
> Al-Qaeda: The True Story of Radical Islam by Jason Burke
I've got this somewhere as well, it's a good journalistic account. Burke I remember as taking a fair minded approach at a time when this was all very politicised.
If you have Amazon Prime you can watch the TV version of the Looming Tower they made a few years ago - it was pretty good.
SteveX - are you interested in the biography of bin Laden alone? Or the context that produced him, if the latter then some of the work by Gilles Kepel or Olivier Roy on the history of political Islam is good. All their major works have been translated into English I believe. I remember Kepel's "Jihad: the trail of political Islam" helped me really get my head around things when my work suddenly plunged me into that world. Roy's Globalised Islam also was very rewarding when I read it a few years later.
