Ooh, if you can do some marathon reading...I recently finished the Twilight series by Stephenie Meyer. It's a teen series and it definitely has some intense bits, but I'll give away the end of the series by saying that is has a very happy ending. It's basically teen romance, but was not intended to be in the teen genre.
The characters (especially the male lead) are very lovable and I became quite attached. :)
We always read to each other at night before going to bed while I was preggy. Our favorite was Dave Barry--he is hilarious. I had to go the bathroom a lot as I was laughing so hard, but it really helped with the nasty nightmares I would have.
