Third in the saga of teleport David, his wife Milly, and now their daughter Cent. Steven Gould is the direct descendant of Robert A. Heinlein and Joe Haldeman--he writes so sensibly and practically of impossible things that he makes you believe, well, the impossible. He's really given serious, extended thought in these novels (Jumper, Reflex) to just what it would be like to be able to teleport, and to just how attractive that would make you to the powers that be. If you live in daily fear of being kidnapped by forces determined to exploit your ability, what do you do with your life? How do you stay out of their reach? Do you decide to try to do good in the world anyway, at the risk of losing your freedom and self-determination? How do you raise a child in this world to be aware and responsible? (FYI, Milly and David do a pretty good job.)
I read Impulse in one sitting. Watching Cent, a very atypical rebellious teenager, learning to cope with her world's privileges and its dangers and even to extend its boundaries is riveting stuff. Cent is a marvelous addition to this world and is now my favorite character in it. I hope we get to go there again.
