Wait a minute, that last one already exists!
There's a Facebook page called What To Read After 50 Shades of Grey and it's a one-stop shop for all your romance and erotic-romance needs. Readers submit books they like and it's as easy as that. There are over 68,000 readers involved!
This week I have the honor and privilege of being a featured author so I invite you to drop by and have a look. It's really 50 shades of awesome :-)
