Beautiful and haunting. It doesn't really strike me as a children's book though. It is a wonderful way to tell the story if the need for story, or the tragedy if oppression, and how it can be overcome.
A city boy finds a stamp that unlocks his imagination; a country boy is captivated by stories. When they grow up, the two boys take different paths – one becomes a prison guard, the other works in a factory – but their early childhood passions remain. When the country boy’s stories of hope land him in prison, the letters and stamps sent to him from faraway places intrigue the prison guard – and a unique friendship begins.
