A great pity this is out of print, as it's one of the best examples of real world-building in a Star Trek novel. It holds up as a work of pure speculative fiction, as very few other works set in this universe do. Instead of reading a juvenile history of some Terrestrial civilisation and crudely imitating it, as appears to be the practice of many Star Trek writers, Duane creates a complete and believable culture. If the people who write scripts for the shows and films had any sense, they would regard novels like this as canon and dump most of the absurd tripe that the creators of the Old Show (largely from outside real, that is to say literary, science fiction) developed.
