Set in the “Freehold” universe, this novel is about first contact with a planetbound race that has almost no metals. They turn out to be quite advanced in ceramics, steam and other sciences, all developed without metals. Humanity, in the form of a joint Freehold/UN mission, makes efforts not to expose the race to metals. This inevitably causes tension.
While not as action packed as other Williamson novels, I found this highly enjoyable. The plot is both smart, entertaining and clever. The characters are perhaps somewhat unoriginal, but do the job adequately. I did have a hard time keeping track of some of the secondary characters. A dramatis personae would have been great. Williamson is at his best when describing the effects of weapons and other technology. Many other authors would have turned this book into a boring scholarly piece, but Williamson manages to keep the technology discussions both entertaining and fascinating. The story has many interesting twists to keep it going.
