Would you do the same?

I've never read the book but I have thought about this question many times after hearing a plane went down on some snow covered mountain and the survivors had to eat human flesh to survive. I honestly think I would do it if it were a situation like I described above. I would do anything I had to do to stay alive as long as I possibly could because I have 4 kids I would have to get back to home to. But if it were like an end of the world thing and there were only a handful of people left on the planet then just kill me. I would never want to be one of the last ones left.

Please, tell us the name of the book. Please, tell us who wrote it. I do not think that I could ever go cannibal.
