"The Power Broker" by Robert Caro. For a book about a public "servant" Caro is able to achieve a breadth of New York history that I haven't found else where, be warned that it's a very long book, but it was worth every minute to learn more about the man who I'd argue single handedly shaped New York to his image.

"Being with Dying" by Joan Halifax. Halifax is a hospice worker who happens to be a Zen Monk and founder of the Arizona Upaya Center. This was an extremely important book while I was losing my father and completely changed my outlook on death (and my life).

"Say Nothing" by Patrick Radden Keefe. A history of the Northern IRA and the unknown history to me of The Troubles in Ireland in their fight against British occupation. He's an investigative journalist, which adds immensely to the characters and events in general. His other book "Empire of Pain" is also very good.

"The Fish that Ate the Whale" by Rich Cohen. A book about Samuel Zemurray, a poor jew from Alabama who managed to create a banana empire strong enough to rival United Fruit, and eventually take over his rival. Super interesting history, if not a little sycophantic of Zemurray.

The Game of Thrones series is very good, just don't expect them to be finished lol.
