Shamsie’s epic story A God In Every Stone starts in 1914 and carries us across the globe, into the heart of empires fallen and conquered, from Ypres to Peshawar. Young’s The Heroes’ Welcome is a sequel to My Dear, I Wanted To Tell You. For those who fought, those who healed and those left behind, 1919 is a year freighted with perilous beginnings, unavoidable realities and gleams of indestructible hope. The authors talk to Ted Hodgkinson.
