This book was interesting, but had really nothing useful for traveller. It was full of funny ideas, like what the nano-bots could do for you like sex changes and brushing your teeth.
It also had an interesting setting. Humanity had been thrown out from earth by some super race of dolphin lovers, so now humanity live on the moon and on the other planets, and were not allowed to go back to earth. The main character is a reporter, who is supposed two write an article series for the 200 year anniversary, since the war with the aliens.
