Since it seems to grab your attention so much, maybe you should read it and then decide if you want to keep it or not. If you still decide not to keep it take it to a Christian bookstore and ask them, many of them will take used ones and and send them to places that find new owners.
I would think though that the simple curiosity of owning a book that you have never read would make you want to at least find out what it is all about. Especially a book that would get you a death sentence in some countries, even just for owning it.
