Used to work in a bookshop ....... this was the worst kind of query! Sometimes people would describe the cover of the book in detail with everything but author and title!
Answer is I don't know. You remember a lot about the book. If you could remember any character's name that would be helpful when searching.
Otherwise I'd suggest real sci-fi nerds are very internetty. Find a site where sci-fi people chat. Give THEM your excellent plot description. They'll love helping.
Look for something like bestsciencefictionbooks.com
Any community would give you lots of brainy helpers. Hope this helps.
