I agree with others, there is plenty of crude jokes and little alien fighting. However, I found it interesting for the most part and engaging for a non serious read. As a way to pass the time it was as good or better than 1/2 the B movies I have wasted my life watching while it certainly isn’t amongst my favorites. Depending on the price, it was okay and I wont be returning it. Again, if you don’t enjoy crude humor to a borderline extensive amount then this book isn’t for you.
