I do vaguely remember seeing the 99PI book club at some point, but I didn't follow it. I'll check it out, though. Thanks for the tip!

I'm really looking forward to working through the LBJ series. I think I'm going to get it on Kindle and Audible so I can work my way through it bit by bit whenever I have free time and attention.
