Waiting for Anya (Paperback) Michael Morpurgo
Jo did not stop until he'd shut the door behind him and even then his heart could not stop pounding in his ears.
Jo finds out that Jewish children are being smuggled away from the Nazis over the mountains near his village. All goes to plan until German soldiers start patrolling the mountains, and Jo realizes the children are trapped. Jo's slightest mistake could have devastating consequences.
