Legend
It is an interesting market. SF&F used to drive book sales but the genre is shrinking. This may have to do with a lot of the material that used to be considered "adult" SF&F is moving to young adult sections or vanity publishers like Amazon eating up the market. I am not sure.I would expect all of these to factor in to their preferences. Literary stuff seems to be moving in similar directions as well, e.g. what I've heard about the Percy Jackson books, the Hunger Games books, the Locked Tomb series, and more.
I find it very difficult to discover new books that I will like and much of it seems written to the same template.
I may also just be getting old.
