The Beginning of Infinity by David Deutsch. The sheer breadth of the ideas covered in this book is breathtaking, and there are some truly mind-bending ideas explored in this book. If you're looking for a good general science book I highly recommend this one. Superintelligence by Nick Bostrom. Few thinkers have thought about this issue as deeply as Bostrom, and it was fascinating to hear his thoughts on AI. Bury My Heart at Wounded Knee. Pretty traumatic read but essential if you really want to understand a dark and overlooked chapter of American history
