Currently reading - Cell by Stephen King. I'm about half way through. It's typical King, but still good.

Leave it to King to find something to go wrong, very VERY wrong, with something that just about everyone has these days - a cell phone. Without giving anything away, the cliffnotes version is that one day, just after 3pm, anyone who is using a cell phone turns into a zombie sort of being. The books is about what happens to those few people who were not using their phones and what they do to survive.
