There is an image used in this book.
A gorilla , holding its infant, is in a cage where the floor becomes roasting hot. At what point will the gorilla stand on the infants body to save itself? I.e. At what point would we throw our loved one 'under the bus', to save ourself? It's an image, perhaps in the book, or an author interview that really disturbed me.
I found this story so cruel, that concept so disturbing, I couldn't really 'enjoy' the book.
I don't remember the end exactly, but if that is a spoiler, I'm sorry, and please report.
