Anyone familiar with the notion of Darwins theory of evolution, in that improvements to species depend on mutations, will enjoy this novel. Also, anyone familiar with the recent X-Men First Class film will find similarities. In fact, I would go so far as to suggest that this is the very first X-Men story and John can be seen as a prototype Professor Xavier. In this and his other books Stapleden is asking where man as a species is heading. How will he evlove? What will he achieve? This story attempts to focus on what would happen if evolution gave rise to a superior being and how that person(s) would regard the lesser specied of Homo Sapien.
John sees us as we see the chimps in the zoo. He has a fondness for individuals but is unable to see himself as part of the race. This leads to acts of violence which we would see as morally wrong but he sees as justified in order to protect himself and his own kind.
His own kind... yes, he does find more. This becomes his calling and after putting his incredible intelligence to work to build a nuclear powered yacht and plane (well, sort of nuclear) he travels the globe seeking beings with similar powers. Like Professor X he is a telepath and uses this to track them down - just like Prof X does in the film. I do think there is a bit of plagarism going on here but I have been entertained by both so I am not bothered.
This is a good book to read if you are an X-Men fan or simply interested in mans next step along the path of evolution.
