Good to Great - By Jim Collins
Andrew Hindes answer is a good one. I would also add that some leadership styles are better than others in certain situations but less good in others.

So with that said I recommend 'The Art of War' by Sun-tzu since this considers leadership styles in different situations.

I recommend the Bible even if you are not religious.
