well i definitely stay away from Romance section in the bookstores... you know, the ones with Fabio on the cover - eeeeew.
Like others said, how do you classify erotica? Lots of other genres will have some romance and erotica thrown in for good measure, and if done tastefully, it can be great. I mean, take Thorn Birds for a example - a great classic, plenty of romance and some erotica, but no one would say its a cheesy book.
If you are asking what specifically "chick" books can be offered, well thats another story. Jodi Picoult is quite good as one example.
But a specific romance/erotica book... i can't think of any. Not to say there wont be a market for it!
