I need a trashy novel or two for a holiday.

Things that I have already read and like that would fit hte bill include:

Lee Child's Jack Reacher series
The girl with the dragon tattoo series
Stephen King/Dean Koontz stuff
John Grisham stuff

I also have a book voucher that would get me two books. I don't want anything too serious or heavy. I don't want to learn stuff or have to think too much about it, I just want to be entertained. Any recommendations?
