I actually read a lot of different genres. My favorite's are murder mystery/horror, fantasy, supernatural(werewolves, vampires, fae, things that go bump in the night. Not "Twilight" vampire crap), whatever genre Jodi Picoult is and so on.
I'm currently reading George R.R. Martin's second book in the Song of Ice and Fire series, Clash of kings. I have a Storm of Swords waiting on me after that.
I'm also a big fan of Terry Prattchett's Discworld series of which I also still have an unread novel lying around.
Laurell K. Hamilton's Merry Gentry series is my dity little secret it has an interesting concept but is pure smut at times.
