Did you come across the 99% invisible book club for The Power Broker? I tried keeping up but fell a bit behind by the end of the year and finished the following January. it's a great complement to the book. Caro is an incredible writer - I'm on the first LBJ book now. It was never a book I thought I could finish just from the intimidating size and seemingly dry nature but Caro's storytelling moves it along so well.

The Power Broker is very good but his LBJ series is phenomenal. When I recommend it to people I say it's like The Odyssey of American History and Politics. It's the best non-fiction series I've ever read and I almost exclusively read NF.
