The technical challenges are well done, but the author conveys no sense of doubt that they will be overcome, or fear that the carboard-cutout plucky hero will not come through in the end. One of the other characters in the book sums up the protagonist as "a problem solver", and quite frankly he is presented as nothing else. There is a rather jarring change from the first-person point-of-view of the hero to third-person views of mission-control, NASA personel, Chinese rocket-scientists etc. This is done to show off more neat problem-solving stuff (and it
was nice to see Chinese people both actively involved in the plot (
Joss Whedon and
Peter Hyams please note) and not simply as yellow-peril villains (Tom Clancy and any number of other Western writers in pretty much every genre ever)), but it blows any sense of the hero's isolation out of the airlock.
