"The Compleat Strategyst" by John D. Williams
One of the objections to "Game Theory" is that is it totally cynical, presumes all life is made up of "zero-sum games" and that each player either wins or loses. While this is very useful in formulating strageties, it doen't really help in "real life". However, the theory is very interesting and is a very interesting starting point for more advanced strategyes.
Mr. Williams approached this subject with a great deal of humour and yet a very informative style. The book is well worth reading. You would be amazed at how many results are contra-intutitive!
