War Horse author Michael Morpurgo on Listen to the Moon

Michael Morpurgo's book War Horse won the hearts of millions and World War I is a subject he has decided to revisit in his latest novel, which is based on a real event.

More than 1,000 people died when a passenger liner was sunk by German U-boats but Michael's book, Listen to the Moon, is a tale of survival.

He spoke to BBC Breakfast about the book and said it was a story of survival, trauma and recovery.
