When I was a kid I read I am david, it was the first book that made me cry, made me laugh - it was the first time that I realised that as well as being entertaining that some books had a powerfull message, I forgot all about it until I saw it next to the boy in the striped pyjamas in waterstones, I must buy a copy and re read it, I wonder if it will move me as much 30 years later
