My rating: 4 of 5 stars
Excellent (as in very plausible) descriptions of an orbital habitat, but only three characters are developed enough to make the reader care about them. As always, Allen Steele gets the science right, builds a compelling intrigue, but the ending seems a bit rushed, and I have to read the rest of the novels in the Near Space series to see if the final revelation pays off somewhere along the way. Nice twist, anyway. And a very enjoyable read, in all.
