Another book I hope to some day soon offer a full review for. I will say briefly, the revolving POV did not work for me, mainly because I didn't understand the point of it. I never felt it offered any deeper insight into the relationships of the three main characters and, except for very minor cosmetics, there wasn't a lot of difference in their voices. (Was this to point out a universal similarity? As I say, I never figured out why the author chose to write the story that way.) 
 The other main thing that annoyed me was that again and again plot points were sprung on the reader like grand "AHA!" moments, but never were actually AHA moments. Anyone paying attention knew well before it was revealed that (view spoiler)[Ruby and Joe (hide spoiler)] were sleeping together, and that (view spoiler)[Helen (hide spoiler)] betrayed Ruby. And, god knows, the bit about the weird dude attacking the other dancer with a knife wasn't so much foreshadowed as telegraphed. 
 Still a fast and comfortable read. Seemingly well-researched and written with an obvious love of the subject and period.
