Not that many, considering how many books I read (at least a hundred a year, probably more). I don’t cry often at books or movies, but there have been a few:
The Education of Little Tree: I’ve read it many times, but still can’t make it through the end without crying.
The Bean Trees: There’s a part where a couple who lost their child pose as a little girl’s parents so she can be adopted. I didn’t cry too much, but got a little teary-eyed.
Cyrano DeBergerac: Had to read it in high school, and it might be the first book (well, play) that made me cry.
The Time Traveler’s Wife: I think I only cried because of the little girl. Things with kids get to me sometimes now that I have my own kids.
Harry Potter and the Deathly Hallows: Yeah, I’m such a dork. I think I cried at the end just from being so invested in the books for so long, and probably from the sleep deprivation brought on by staying up half the night to finish it.
That’s all I can think of right now. There have been a lot of books that have disturbed me very deeply (Holocaust books will do that, as well as books about things that commonly happen to children in some third world countries), but for some reason they don’t actually make me cry.
