I like that Hitchens' careful research leaves no stone unturned. I
have watched a lot of Hitchens' debates on YouTube, and many of
what is written in the book were already said in these debates. On
addition to Hitchens discourse, he also provides his readers dozens
of books and articles which he had used for his book research. All
in all, if English is not your strong point, (Hitchens use a lot of
unfamiliar words -- the book's vocabulary is way too rich for me) I
suggest that you have a dictionary at hand (thankfully, I am using
Kobo Touch which has an awesome dictionary).
I hold a high respect for Christopher Hitchens. Many people may or
may not agree with everything that he says, but he does have many
persuasive argument when it comes to religion. I highly recommend
this book.
