I remember reading this with my friends back in the years.
The book was a little too short, but was one of the best WWII books I've read. I haven't read it in years, but I will sum it up.
Sadako Sasaki. She is a girl who grew up in post-war Japan, after the bombings. She lived a mile away from Ground Zero.
She contracts leukemia, and starts folding paper cranes. In Japan, it is said, that if you fold a thousand paper cranes, the gods will listen to you, and heal you.
She couldn't, according to her book, only folding around 700 before becoming too weak. I remember the last line of the book, clear as day,
"She never woke up."
However, according to her family, she folded more than a thousand before dying.
Anyway you slice it, she lives on, as there is a statue of Sadako at the Hiroshima Peace Park.
