I think I said this after the last Ringworld book. Why do I keep buying Larry Niven books? I just keep doing it. I keep reading them too. This time is was Building Harlequin's Moon by Larry Niven and Brenda Cooper. To be fair, it was a lot better than the last Ringworld book but then that isn't exactly praise. Perhaps working in collaboration keeps ol' Larry on track. Actually I suspect that Brenda Cooper did most of the actual writing and Niven supervised.

The story is coherent and clearly written like an earlier Niven story. In fact there is a lot more that is like previous Niven stories. I kept thinking "oh just like A Gift from Earth", or "just like Legacy of Heorot" or Rainbow Mars or Ringworld. Self parody maybe.
