I felt the need for a little Scalzi snark and this is the snarkiest of his novels. It delivered on that in spades along with the entertainment. I inhaled this in one sitting, and there were definite snorts and giggles as I went through it. Yes, its only 4 stars on the top line but that's because a reader needs to be in on the joke. You have to be into Star Trek etc for any of this to make sense. Quality Scalzi, can recommend.
