When a frail old man is found sleeping on a bench near Cessie's home, her parents take him in, and Cessie discovers the stranger is Popsicle, the grandfather she never knew she had, vanished from the family for fifty years. As the two of them grow close, Popsicle begins to share the secret of his past and the role he played in the extraordinary rescue at Dunkirk. But when his health fails and he is moved into a grim care home called Shangri-La, Cessie is determined to set him free and help him make one last journey back across the Channel to the place that shaped his life. A deeply moving story about family, memory and the bond between the very young and the very old, told with all of Michael Morpurgo's warmth and heart.
