Clemente: The Grace and Passion of Baseball's Last Hero (2006) by David Maraniss

This is a biography of the great Pirate by David Maraniss, the same author who wrote the biography of Presidents Obama and Clinton.  As in the other ones, you get a good feel for the times in which Clemente lived.  Also the circumstances of the plane crash are interesting.  There's more to it than just the plane went down.  This is a good read.
