Query: Ghastly space opera

This is a book that might even have had trouble being published in the 40's, the heyday of space opera. The script would probably not have been accepted for a very bad episode of "Star Trek." That is has been published at all, in any decade, is a mind-boggling tribute only to the venality of publishers who will count on a well-known name to sell any old drek. That any respectable writer would allow this donkey to go to print is inexplicable, save that he suspects he will never write another book so doesn't care. The 'human' characters are trite, shallow and stupid, the 'alien' characters are idiotic, the plot - such as it is - is mind-numbingly predictable, the suspense and tension are zero. I give it one star for grammar and spelling. It deserves far less.
