Janesville: An American Story. This is about Paul Ryan's hometown and how it flourished until the Great Recession and what happened after. If you want to try to truly understand the thought process of Paul Ryan and expand your political horizons a bit (if you're liberal), then this is a good read. Full disclosure, I haven't finished yet, but mostly done and it has at least helped me understand his thinking a bit more.

Children of Blood and Bone: Really good and gripping. Listened to the audiobook of this one and it keeps you on your toes.
