There are plenty of new novels. Visit a bookstore. Most of them will be forgotten, but some will be read a century from now. Novels face more competition from other forms of entertainment than they used to. But they still sell in volume. It's not like books of poetry.

Knockoffs are a problem. About fifteen years ago, "Teen Paranormal Romance" filled six bookcases at Barnes and Noble. That didn't include the vampire content in Romance, Fantasy, and Best Sellers.

She said the Hunger Games knockoffs were starting to come in and would be pushing out the Twilight knockoffs. She was right.
