Just started Master of the Senate. Caro's books have reignited my love of reading. Cannot recommend his books enough for anyone interested in how power in organizations or government is culled and cultivated. His books read like thrillers, but are exhaustively researched and sourced.

Sony Pictures recently released a movie covering Caro and his recently passed editor, Robert Gottlieb, relationship and process: https://www.youtube.com/watch?v=gv3CRojrbeE
