How long before this disappears from Barnes & Noble?

I never quite get over that this represents an entire section in a bookstore. Teens experiencing romantic awakenings with monsters and ghosts. If a pastor in the 80s would have warned about this in some breathless sermon about the dangers of the occult we would have laughed at him.

I have to wonder how long before this stuff is no longer cool and is replaced by Teen Transhuman Romance or Teen Boring and Normal Romance.
