Query: Not a biography, but quite interesting nonetheless

Be aware that if you are looking for a linear, story of the life of Napoleon III sort of book, this is NOT going to do it. If, on the other hand, you have a general interest in Napoleon III and his regime in terms of how the affected social life, literature and politics, this is a very interesting overview of a variety of social realms during the Second Empire. Sort of a tough academic read, but well-done and interesting to the fan of French history or the Napoleons.
