"VirtualPress," the publisher of the paperback edition of "Don't Mess with Earth," is what we often refer to as "vanity press." Simply put, it means the author probably could not find a real publisher and had to pay for publishing it himself. For this book, it's a good bet such is the case. The writing is amateurish, awkward, and full of grammatical errors and it seems unlikely a real publisher would bother. If these things don't bother you and you like space operas, even inane ones, you may like it. Otherwise, spend your money on something else.
