Pippa, I'm in a slump, too. My TBR list is unusually small for this time of year (although Raven Boys is on it--I adored Scorpio Races), and I'm just not finding a lot right now that I can really sink myself into. I have authors I love, but they don't happen to have books coming out right now, and erm, don't stone me, but I've never cared much for dystopian. And my library is reeeeally small and slow to acquire books (on the new shelf now are a ton of creature-love-triangle books, which has been in a bit of a glut for quite some time). I want something that makes me feel the way I did when I read my favorite fill-in-the-blank-with-past-hot-genre-books, *including* the sensation of reading something that was new and not done to death.
OTOH, it's also true that sometimes like Mysteryrobin said, your mind is in a hard place for reading, and things that you might like at other times just look blah. Hopefully we get out of the slump soon!
