Lonesome Dove. The Invisible Bridge. To Kill A Mockingbird. Gosh, there's a lot more than that, I tend to cry easily.
The Notebook got to me too. I read right after my grandmother died; she had Alzheimer's.I remember crying to The Notebook (read it 2 yrs before the movie) and Message in a Bottle by Nicholas Sparks. The Five People You Meet in Heaven by Mitch Albom was good as well. There were more, but I can't seem to remember.
