The sad fact that people interchange the word democracy with capitalism allows many authors, including Noam Chomsky, to decry the former, when it is really capitalism or big government that they want to attack.
Even when the proper subject is covered, the argument is more about forms of democracy and why one is preferable to another, e.g., constitutional monarchy (British) vs. three-branch representative system (U.S). See Walter Bagehot's book, The English Constitution.
The reason we don't see too many history books promoting totalitarianism, aristocracy, plutocracy, or even meritocracy is that the authors would be quickly discredited. About the best one can hope for are books comparing various systems. Try Aron's book, for example.
A search of Amazon lists a number of anti-democracy books:

This might be a useful place to begin research on what appears to be an interesting (but, frightening) line of thought. It figures that Wikipedia also has a page devoted to this subject:
