1999, Amy Thomson, Through Alien Eyes, New York, N.Y.: Ace Books, →ISBN, page 85:Moki and Ukatonen weren't supposed to go out without Eerin or Analin, so they spent most of the day watching the Tri-V or listening to Analin and Eerin talk about them. It was fun at first, seeing themselves on the Tri-V, but they only showed the same few pictures and words.
