Part of a stunning new design collaboration between Puffin and the Imperial War Museum, this is an unforgettable novel by a Carnegie Medal-winning author, with a special foreword by Elizabeth Wein, author of Code Name Verity. In Scotland, in 1915, a group of teenagers from very different backgrounds meets for an idyllic picnic, but the war raging across the sea proves increasingly impossible to ignore. Soon, they will become embroiled in what will become known as the Great War. Determined to carve their own paths in a time of great upheaval, the five friends face not only the horrors of the trenches but also the flame of first love, as well as the political struggles of pacifism and women's rights. Their lives will be changed forever—and nothing will ever be the same.
