Three stars is pretty amazing since I don't really like short stories. (Reading these started to make me think I have just read some really crappy short stories in the past.)
For the most part, I thought the characters were very honest and not preposterously exaggerated for effect, which I very much prefer to the pandering of some short stories (and full novels). The stories all play neatly on ideas of innocence and maliciousness and sexuality and all the different ways you can hurt someone or be hurt. That said, the whole thing was kind of a downer. (I think there are two stories that don't end in utter tragedy, but even those have a lot of distressing stuff going on in them.) I didn't want to stop reading, but I was constantly stressed out for the characters, and I'm definitely impressed by Orringer's ability to create that feeling.
