I can be kind of persnickety about the books I read, and quite often get bored with modern fiction. It has to have an element of time travel, romance, history, reality, humor. I love to hear about ghosts and all that spooky paranormal stuff. I really love relationships. If the back cover says something about a love twist, I'm in.
Perhaps I feel I've met my quota after working at the library and having access to every book known to man. I can honestly say I've read just about everything, and now have settled into stubborn reader land.
Are you picky? Or do you try to expand your horizons as a writer?
