MINNEAPOLIS (KMSP) -
A series of racy books is racing up the best seller lists, but they may be too risqué for some local libraries.
Some people call the "Fifty Shades of Grey" series "mommy porn" because the books have a large female readership and also contain graphic sex scenes that are a far cry from the old harlequin romance novels.
So far, 10 million copies of the books have been sold, making the word-of-mouth sensation one of the fastest-selling series in publishing history.
What started out as fan-fiction for the 'Twilight' novels is now becoming as popular as the series that inspired it. The "Fifty Shades of Grey" trilogy tells of the romance between a manipulative millionaire and a young college graduate, and its erotic scenes feature bondage and S&M.
Yet, the book is so racy that some libraries are refusing to lend it out. A library in Fond du Lac, Wis., is opting against carrying the books because they don't meet community standards.
In the Hennepin County Library System, it's the most popular book in circulation. According to the library's website, more than 2,000 people will wait up to 2 months just to read it. In fact, all libraries in the metro have their own copies with long waiting lists.
