Building Harlequin's Moon

I bought this out of curiosity, as a long-time Niven fan, to see if it was better than some of his other more recent offerings.

It was. Good, but...flawed. For a book this long, a bit less conversation and a bit more backstory would have worked well - although Brenda Cooper's contribution may have been to make female protagonists more real. IF there are to be sequels, then we can see what happened to Ymir and to Sol system - because we certainly have no idea after this one.

Some of the mechanisms used to advance the plot were also a little contrived. Glass tubes, that are breakable, having to be carried by people? In an environment where there are tugs that can move moons, and nanotech? And surely ceramic would have been better?

But anyway. It's a good, pretty long story, with the interesting juxtaposition of people who can plan a 60 000+-year project, be around to carry it out, and...OK, you'll have to read it to find that out. A good book - just not a Ringworld.
