Mark beat me to the punch about Perreau-Saussine’s new book, so instead I will recommend his superb intellectual biography of Alasdair MacIntyre from a few years ago, which, so far as I know, has not been translated.  That ought to be rectified immediately.  American readers would appreciate his thoughtful and penetrating remarks — an illuminating take on MacIntyre that is distinctively French in certain ways (I believe, but am not certain, that Pierre Manent was a teacher, or at least a colleague, of Perreau-Saussine, and it seemed to me that one could sense the influence here and there).
