I've read both this book and Tomislav Sunic's book, "Against Democracy and Equality". Although the intentions of both books are the same; to provide the reader with an overview of, and insight into, the European New Right (and in so doing, also gain insight into the nature of the political movements in the United States as well).
Unlike another reviewer of this book here, I do not think it necessary to read Sunic's book first. In fact, I would strongly recommend against this, as I found Sunic's book to be almost unreadable. He's an intelligent man, I'm sure, but I found the language in Sunic's "Against Democracy..." to be so needlessly elevated and abstruse as to make reading an exercise in mental torture.
O'Meara's book, by comparison, is very readable. To be sure one needs to be a literate person to read this book. But frankly anyone expressing an interest in understanding the New Right is already revealing a degree of intellectual capacity and inquisitiveness that should make the reading of "New Culture, New Right" not only possible, but at times a pleasure.
I gave the book only four stars because I am not a promoter of "grade inflation" - whether for students or books. It's an excellent book - and I recommend it without reservation, but I'll reserve five stars for books that are truly exceptional.
