This is the long-awaited new novel from Hugo Award-winning writer Greg Egan! The Amalgam spans nearly the entire galaxy, and is composed of innumerable beings from a wild variety of races, some human, some near-human, and some entirely other. The one place that they cannot go is the bulge, the bright, hot center of the galaxy. There dwell the Aloof, who for millions of years have deflected any and all attempts to communicate with or visit them. So, when Rakesh is offered an opportunity to travel within their sphere, in search of a lost race, he cannot turn it down!
