Here are a few that I read in the six months to a year or so. 

Liar's Poker, Michael Lewis - An older, but entertaining book on investment banking in the 80s.  The stories in this book would make me sick if I weren't such a pessimist.  Things haven't changed.

Outliers, Malcolm Gladwell - Succeeds in presenting a pretty interesting analysis of success.

Getting Things Done, David Allen - A book on how to be better organized.  Unfortunately, it is pretty terse and ironically, to finish reading is one thing I still need to get done.

Dave Pelz's Putting Bible, Dave Pelz - If you didn't think putting was interesting, you were right.  However, this book is an excellent resource of putting advice.
