EDISON - A novel is getting a lot of buzz across the country for its racy sex scenes.

"Fifty Shades of Grey" is currently topping the best seller lists for USA Today and Amazon.com even though the books have been called "mommy porn" for their sexual content.

Two counties in Florida have banned the novel from their library shelves.

The move comes as author E.L. James sets off on her U.S. book tour.
