The Blocksize War by Jonathan Bier I really enjoyed. Almost a historical explanation of how bitcoin is what is it today.

I also think some of the best books that led me to bitcoin weren't about it alone, but more about complexity science and the history of economics. Some include: --> Lords of Finance - Liaquat Ahamed --> Incerto series - Taleb --> The Death and Life of Great American Cities - Jane Jacobs --> Unsettling of America - Wendell Berry --> The Timeless Way of Building - Christopher Alexander --> The Diversity of Life - E.O. Wilson
