nineteenthly 's review for:
Ringworld
by Larry Niven
Clearly a classic but on first reading it, I failed to recognise that it fit into the 'Known Space' series very neatly, a universe of which I was later to become a major fan and which kind of overlaps with Star Trek, though this is of far better quality. Fairly hard SF about a big dumb object whose scale is amazingly vast, with interplay between the species visiting it and those native to the structure itself. It's definitely a boy's story, but that's not to detract from it.
