The popularity of "Fifty Shades of Grey" has brought new attention to the lure of erotic/romantic fiction. According to a new report by CNBC, romance is the best-selling fiction genre. It generates about $1.4 billion each year. With the rise of e-books, women are reading such novels more than ever. Not only can they purchase raunchy material without the embarrassment of doing so at a bookstore, but as erotic author Dr. Ivan Rusilko reveals: 

"With the different types of tablets out today you can get away with a lot more risqué type of literature to read. Instead of sitting on a plane with some Fabio cover model on the front, you have an Apple symbol." 

There are several titillating e-books available online at the moment. Here are three of the site's top sellers.
