1. Misery lit
This makes me sound horrible, but I have no interest in reading about the terrible things people in real life went through in their childhood.
I don't like being scared, so I avoid horror. I've read one horror in my time - Stephen King's Misery - and that was because it was required reading for university, and it terrified me.
I love dystopian fiction, but zombies don't hold much interest. I tried Gena Showalter's Alice in Zombieland recently to see if that could change my mind, and it didn't.
I love romance, and I'm a big fan of people like Nora Roberts, but I can think of nothing worse to read than 50 Shades of Grey and its ilk.
5. "The next ..."
I don't mind recommendations of the "if you like this, you might like this" sort, but books should stand on their own merits, so I don't like being told something is the next whatever. Chances are it's not.
6. Angels/fallen angels
Okay, I can't categorically say I don't like this category, since I can't recall having read too many books in the genre, but it doesn't appeal hugely. I have Fallen on my bookshelf, but it's so far down my TBR list I won't get to it for years, it seems like.
I'm fine with the Harry Potter series being the only books I'm willing to like in this genre in the near future.
8. Beat literature
I've tried reading Jack Kerouac and the like, and just can't get into this style.
I don't mind sci-fi, but I'm just not interested in aliens, or aliens that come to take over the planet, even though I'll watch that kind of stuff (Roswell, Battlestar Galactica, anyone?).
10. Lurid covers
Not a word or subject, but I dislike covers that make my eyes hurt. Get a proper designer!
