Book excerpt: A new wartime classic from two legends of children's literature! Michael Morpurgo and Michael Foreman have teamed up with the British Legion to tell a new story inspired by the history of the poppy. When John McCrae wrote his famous poem "In Flanders Field" among the trenches of war-torn Belgium, neither he nor a local village girl who saves a discarded draft of it could know what enormous power that poem would have on generations to come.
