In SF, I like things like robots and aliens, far-flung planets, struggling spaceships, strange futures, and invented worlds. I don't like things grounded too heavily in reality. The previous Brunner I'd read, The Long Result, had aliens and their visitations to a future Earth that was struggling with xenophobic attitude. It wasn't amazing, but I liked it. It's the sort of thing I wanted.
This short story collection was a mix. The first story, Prerogative, about a man dying during a science experiment and the local yokels viewing it as an act of God, had me worried that I was in for some boring science-heavy reality-based tales. Another story about Russian and American tensions in space also bothered me. Right now, I don't want to hear a single thing about Russia. I don't want to be reminded of their never-ending conflict with the West in a book that's over 50 years old.
Thankfully, it picked up.
You could have told me these were all written by different people and I would have believed it. The prose is straightforward and indistinct. After awhile, you start to notice that there's a playful kind of nihilism that's consistent to many of the stories. The view of humanity is never great, and that aligns for me. It's often highlighted by the presence of likable aliens, another trope I enjoy.
Highlights include A Better Mousetrap, about how one might deal with a nuisance species; Coincidence Day, about alien zoos that aren't what they seem; and Treason is a Two-edged Sword, about an intergalactic war that's more complicated than it first appears. In fact, things being more than they seem is probably the most common theme here.
I wouldn't deter another from reading this, but I wouldn't necessarily recommend it either. One of Brunner's "Best ofs" is probably better.
