I did not enjoy it or see any point in continuing the book after the ship of children landed on the planet of the dogs (about page 25), but then I do not enjoy or see any point in most sci-fi. (Sorry if that sounded condescending to those that do.)

Loved Vinge's short story "Cookie Monster" though -- probably because being fundamentally confused about the nature of one's situation resonates with me, and Vinge explored an interesting theme without trying to impress me with his ability to imagine detailed exotic worlds.
