I read the first half or so of a book somewhere around 1997-99 when I was about 10-12 years old. I think it was old already then.
As I remember it, it's about a young girl who awakens at the spaceship"s destination after being in stasis for a very long time (50-500 years). She learns from the ship's AI that her friend, a young boy I believe, woke up around 15-20 years before her. She then starts exploring this new planet.
That's about as far as I got.
