This story was good in so many way....the world that author  created was spectacular,so precise and complete.the story hold sadness in it's bones ,an old an mature sadness,the kind that always lives in you.
It indirectly show that when you lose your loved ones, besides the sadness and grief you have some hope too , you have some sort of  commitment to them ll,like you have to live your best to make the happy and proud.
Some thing in the story is unanswered to me....why didn't they just let go of everything and live somewhere else or hide?why?why they were so ok with donating their parts?why?
