backlash against a book

"And the backlash against my book by Muslim fundamentalists reveals the deep-seated fear that such people have of mainstream Muslims’ efforts to take back the discourse from those who cannot accept shades of grey in life and faith." Backlash against your book? First, you have a book? Is this now a new ploy? You claim that Islamic fundamentalists are furious about a book that no one has heard of? (thanks Sam)
