This is a great story about a humanity that has overcome war to colonize the stars. I always find the prospect of a universe bound by the laws of relativity a somewhat depressing concept. And yet, the humans of the story go on with their lives and toil enduring decades of travel between destinations. What is more amazing than their discovery of alien artifacts is their daring and ingenuity that allows them to grasp a technological prize and overcome one of the great obstacles nature has placed on matter. The hard sci-fi part of the book is very well written. The book may seem slow in the beginning, but read on. I think you will also find it is worth it.
This novel is a fantastic romp, one filled with many wonderful turns of phrase, and one which relativity plays a part. Remember Disney's The Black Hole? Well, this particular take on objects hanging at the edge of the singularity, where NONE COULD POSSIBLY BE, is captivating. If you enjoy hard science fiction, Wil McCarthy is a writer you should add to your stable of go-to authors.
