Just came in the mail (apologies to Instapundit for borrowing this conceit).
It’s by Robert Spencer. I like the blurb on the top of the book:
“May Allah rip out his spine from his back and split his brains in two, and then put them both back, and then do it over and over and over again. Amen. — ‘praise’ for the author on RevivingIslam.com.”
