Another wandering-the-SF-section pickup. (Goodreads doesn't seem to have a picture of the early-80's insanity that is the cover of the version I got.)Very slim and I *still* couldn't finish is. First off it feels very, very dated, as one of the future threads has a still-functional USSR sending out spaceships in 2090 - although I did like that since it wasn't actually an atmospheric craft they made it in the shape of a hammer and sickle so the Americans would see it hanging there.There were a few clever flourishes like that, but it was not enough to make me finish it. I got to page 115/183. There were three distinct sets of characters, each group having 5-7 people, and about two of characters were sympathetic. The plot was confusing, the three disparate strands didn't seem like they were ever going to converge, and I just couldn't make myself care enough to finish it, despite traveling and having nothing else to read. Ugh.
