Books by author: Jack Chalker

This is one of the better time-travel novels I've read. Chalker takes the paradoxes of time travel very seriously, and attempts to create a story that avoids or resolves most of them. The end result is good in that he is largely successful. The plot is engaging, and its twists are interesting. Where the novel fails is in depth of characterization and both sentence- and page-level craft.

This was not a particularly good book. It presents an unconvincing future where "body-switching aliens" have invaded Earth, and the government is working on technology to match the alien ability. I would not recommend it to others.
