Confluence — Paul McAuley

3 short novels in one volume. Confluence-a long, narrow man-made world, half fertile river valley, half crater-strewn desert. It is a world at the end of its time, a place of savagery, bureaucracy and war, inhabited by countless flying micro-machines and ten thousand bloodlines ruiled by devotion to absent gods. This is the home of a singular young man named Yama. An infant who was discovered in a bier on the river, he was raised by the prelate of Aeolis until it was learned that his ancestry was unique. Yama appeared to be the last remaining scion of the Builders, closest of all races to the worshipped architects of Confluence. Now, awed and fearful of his increasing ability to awaken the machines the Builders left behind. Yama searches for his identity and a history that is both his and his world's.
