** spoiler alert ** 
 I was on board for all of this book except the violent rape sections. While I love the dystopian vision of genetic engineering backlash, I'm not sure I really understood all of the calories as currency stuff. The world of the book seems so dense, foreign, and far-removed from today's time period, I fill a whole series of books could be written to fill in the interesting gaps between now and then. 
 On another interesting note: There is a mix of Thai, Chinese, and Japanese spattered throughout as the narration shifts perspectives from one character to another in a city filled with immigrants.
