One of the frustrating things about writing adult fantasy is that there are a number of agents who say they take fantasy, but if I look at who they represent and which queries they're requesting pages from, it's nearly all YA fantasy. And many have YA fantasy specifically mentioned as what they do, and while they don't say not to submit adult, some don't seem terribly interested in it.
I assume it's because YA is far more lucrative right now, at least in fantasy. It's hard to know for sure from QT, though, because they treat YA as a genre, so if your novel is YA fantasy, you have to choose between tagging it as YA or fantasy for their database.
I've noticed more adult fantasy written in first-person pov, even multi-person first- in recent years. I wonder if that's due to the influence of YA? Or is a greater fondness for first person narratives what's driving a lot of adults to YA in various genres (I may be wrong, but a lot of the YA I've read is in first person, often fairly deep, and sometimes even present tense). I like first person narratives (would have written mine in that if the story mechanics had made it reasonable to do so). Present tense is still something I notice at first in a story, as it just feels a bit weird, but when it's done well, it usually becomes invisible after a while.
So are we going to start seeing more adult books written in the kind of narrative voice/style currently associated with YA?
