Speaker For The Dead by Orson Scott Card
Review Summary: Speaker for the Dead is good, but I think overly ambitious. Too much is going on, not enough is developed thoroughly, too much is being blatantly thrown into the mix to prep for the following novels, and the ending is abrupt and unsatisfying.
Marooned In Realtime by Vernor Vinge
1986, Bluejay Books
Review Summary: Overall, the novel raises, but does not delve into, a number of different technological issues that are worth considering and debating, but its true value is as a light, smart read, with mostly likable characters and a pleasant ending.
