As serious scientific fiction, it is very well written. The prose flows well, the dialogue believable, the characters interesting and all representing a side in the debate of the ethics and emotions of the above scenario. All with a prevading sense of menace.

The fiction is based on generally established science and the book very helpfully provides a glossary for readers who do not have a science background. Though readers with degrees in relevant areas may today spot discredited ideas, it doesn't ruin the story which is about society within and without a new species of human. Uncomfortably, but bravely, the novel revolves around an inverted eugenic-panicked America. Or, put in a historical context, it is as if the American government acted like Nazis but imprisons a master race instead of embracing it. A scary, difficult scenario.

Fans of "The X-files" and "The X-men" would enjoy this novel as an extension of their favourite scenario. Indeed, "X-men 2" movie is an action-packed slant on this tale. Readers of Stephen King's "Firestarter" will see overtones of one of the main characters - a young girl with special abilities. Bear approaches the topic from his own angle and doesn't waste a word.

The novel is however relatively short, and there are many areas where it could be expanded. In other words, a sequel is possible given the wealth of material present. The novel however, doesn't go anywhere near Apocalypse in spite of the blurb.

Overall, a good read basing itself on good science.
