Sooo I suggested Christopher Moore in the other thread. I'm thinking Neil Gaiman is probably an even better suggestion, if you haven't already read some of his stuff.

If you have a Kindle, you should pick up Stardust because it's excellent, and on sale for $1.99! It's so much better than the movie as well.

I would also recommend American Gods which is so so so so so good.

But my favorite Neil Gaiman anything is the Sandman graphic novel series. Even if you're not into graphic novels, these are fantastic. I'm not sure if they would really help you relax, but they'll definitely keep you entertained :P

I think all of the Amazon links should have summaries, which will probably do more justice than I could.
