What is whipping moms into a frenzy these days?

It's the latest book series called the Fifty Shades of Grey trilogy. It's being hailed as "mommy porn" among a growing crowd of wealthy, well-heeled NYC ladies, who say the racy stories provide a sexy escape from their everyday lives.

But the erotic books aren't just for fantasizing. According to some women, reading them has actually revitalized their sex lives.

This could change the whole meaning of book-club meetings. Have you read this series yet? Everywhere I go, women are telling me that I'm the last to hear about it!
