It is a strange book, because, while it is plotted like a 19th century novel, there is something very 18th century about it, that I could not quite put my finger on.
The book is good and very French. It is a kind of subtle satire and then also a critique of class and social hypocrisy.
However, it failed to really engage me at some level, so it was a bit of a chore to get through. I was a little indifferent to the main character. I don't know why. It seems like you should love or hate him. There was just something about it that failed to engage me. It may be simply that Stendhal's demons aren't the same as mine. I don't know.
