Query: The ending made no sense, poor editing, magic stuff happens

This was one of the poorer books I have read. I really wish I hadn't paid 25 cents for it, and that I had back the hour I spent reading it.Tech stuff just happens for no reason. There were two endings, neither of which made sense and both were rushed. Terrible editing, including the reference in the last sentence to a reporter wearing the 'defense metal' she was just awarded.William Keith started the series as 'Keith Douglass'. The publisher fired him off the series for wanting money after 7 books and farmed the work out to whoever was cheap. It seems that at number 20 no one cared anymore, including the publisher or the author.
