Another book I missed at the time of its publication: Charles Drazen’s Mapping the Past: A Search for Five Brothers at the Edge of Empire (William Henemann, August 2016). It’s a family history: Drazin’s grandfather and brothers were military surveyors from rural Ireland “who travelled around the world as officers in the Royal Engineer Corps—surveying, exploring, mapmaking, fighting— in the twilight years of the British Empire.” [WMS]
