I like the story so far, it starts with Mizuki realising that something is bothering her Grandfather. Whatever burden he is carrying is making him sad and affecting his relationship with his granddaughter. Thus begins his story, of how the past affects the future and the legacy of dropping a nuclear bomb on Hiroshima. I would like to find out more about his story. I like the cover of the book and the starkness of it, and what it represents.
