To my shame I've never read this book.
DS2 (10yo) was given it as a present and we've been reading it together.
We've only got to chapter 6 but it's had me in tears several times. DS seems unaffected and finds my tears amusing 
I'm wondering if we should continue. What do you think? Is it suitable for a 10yo?
We had a discussion tonight about why he doesn't find it as sad as I do. He said he does find it a bit sad, but he knows it didn't really happen "obviously the war happened, but these people never existed"
Perhaps he's better balanced than I am?
