I enjoy the early sci-fi genre and this book was in that vein. I thought the intitial plot/premise was interesting but agree with others that a sequel should have been written: many directions available to the writer. Would recommend if you enjoy this time period of science fiction.
I had just finished Hamilton's City at Worlds End, which I enjoyed, and gave this a try. I was disappointed in the basic premise and had hoped for more. It is a short read, however, and if you are a fan of these early short-story sci-fi works you may want to give it a quick read.
