World War I is beyond the memory of almost everyone alive today. Yet it has left as deep a scar on the imaginative landscape of our century as it has on the land where it was fought. Nowhere is that more evident than on the Western Front - the sinuous, deadly line of trenches that stretched from the coast of Belgium to the border of France and Switzerland, a narrow swath of land in which so many million lives were lost.

For journalist Stephen O'Shea, the legacy of the Great War is personal (both his grandfathers fought on the front lines) and cultural. Stunned by viewing the "immense wound" still visible on the battlefield of the Somme, and feeling that "history is too important to be left to the professionals," he set out to walk the entire 450 miles through no-man's-land to discover for himself and for his generation the meaning of the war.

Back to the Front is a remarkable combination of vivid history and opinionated travel writing. As his walk progresses, O'Shea recreates the shocking battles of the Western Front, many now legendary - Passchendaele, the Somme, the Argonne, Verdun - and offers an impassioned perspective on the war, the state of the land, and the cultivation of memory.
