if you are looking for a book of answers or an in depth plot of a speculative world, realign your expectations. while this book is labelled as science fiction, i really would not call it so. the speculative background is to help establish a setting that explores some intrinsic questions about humanity and what makes us human, the horrors and the good that humanity can do to one another. 
i will say this book was a hard read for me at times, and i cried at some of the integral moments of the main character's story. the humanism that she explores reminds me much of the yellow wallpaper, if you enjoyed that short story.
