The premise behind this book is, ahem, simple. Fifty thousand years from now, humanity is dying off as the result of plagues, toxic chemicals and radiation. However, time travel has been discovered and the “Gate Project” is kidnapping people who were going to die anyway in the past. For example passengers from the Titanic, victims of air crashes and so forth. These abductees, who are far more healthy than their short lived and sickly descendants, are put in storage for a future repopulation of the Earth. The story initially revolves around an impending mid-air collision between a 747 and a DC-10 over California. The two protagonists tell their stories in first person format more or less alternately. Bill Smith is the head of the crash investigation in the 20th century, and Louise Baltimore is the head of the “Snatch Team” from the Gate Project in the future.
So far so good. The characters are, as is typical for Varley, deeply flawed and authentic. The story is laid out as logically as possible, although the mechanics of time travel make this tricky. Once Varley has established the premise, the plot is about a developing temporal paradox that threatens the already bleak future with complete annihilation.
The first four fifths of the novel are quite enjoyable. It is clearly laid out where it could easily have been confusing and Varley skillfully ensures that the doomed humanity theme carries over into the characters and the story. The references to old fashioned computers don’t distract since Varley is always about the people, not the technology. The ending did annoy me a bit, since I dislike deus ex machina. But I must admit Varley pulled it off very well, especially by inserting a quite literal meaning in the whole thing.
