Newsweek: Fifty books for our time discussion

Just about finished with the Looming Tower by Lawrence Wright; an excellent read that I will post about later. With 35 pages left, I am considering which book to read next. I am considering 2 biographies, either Whittaker Chambers or American Prometheus (about Robert Openheimer). Anyone read these, thoughts?

I haven't read either, but I am fascinated by Openheimer. Also, if you haven't read Predictably Irrational pick that up. I'm about halfway through and it is fascinating.

I do have it and started to read it over the weekend. Fascinating. Thanks for the recommendation.
