This book definitely falls under the heading of "Interesting concept, but not good creation." The world of the book is barely described in any sort of detail. The aliens are cookie cutter versions of humans in appearance and actions. The idea that people might be unwilling to get involved with a marital dispute where the husband is beating his wife to the point where she loses her children, but are willing to use a massive tank to blow up another culture simply because their alien friends say that the culture is bad is silly. I couldn't even finish the book. Like I said, this book had so much potential but just never managed to carry it through.
