Michael Morpurgo's novel Shadow has won this year's Red House children's book award, which is voted for by young readers.It is a third win for Morpurgo, who becomes the only author to do so in the award's 31-year history.
Shadow tells the story of boy who is befriended by an army sniffer dog in Afghanistan.
"Shadow was a difficult book to write because I was writing about a contemporary conflict," Murpurgo said.
He was presented with the award at a ceremony in Birmingham on Saturday.
His book, which is partly set at a detention centre for asylum seekers in the UK, was published last September.
