I read this when I was in primary school. It must have been a set book for our standard, because I remember reading it in class. It made quite an impression, 'cos I often thought about it years afterwards. So I added it to my Amazon wish list* and got it for Christmas.
I finished reading it last night. I'd forgotten a lot of it and found myself sobbing through the last few pages. Then I fell asleep until Lee came up looking for me.
*It's newly updated...my birthday's coming up (in six months).
