Oh, Yeah! This is what I’ve been looking for: hard science fiction which clamps on to you like a pit bull and won’t let go.
(There be spoilers here. Maybe)
In the far future (maybe) beings seek and interact with a culture of semi-sentient of arthropods (maybe) who have to progress from early Iron Age through the theory of something like relativity in a single generation … or die. Oh, and invent non-Euclidian geometry and calculus in the bargain. Unlikely? Who cares? It’s a great story. In fact, two great stories interwoven.
The drought of engaging, mind-hurting hard SF is over. For a little while.
Love the cover art.
