Zen in the Art of Archery- Read this like three times a year. My book is bent, but always a good read.
Invisible Man- One of the most important books ever written, period. A must read for any man, a multi-read for any black man.
Breaks of the Game- Sports book, but it teaches you about hardship and loss better than most novels. Brilliant reporting, as well. You're going to look at interviews and reports today in disgust.
