Well, what can I say about Mr. Gerrold? Obviously, I enjoy his writing, or his name wouldn't appear here. The two series I have read books from were both fairly good. I started off with The War Against the Chtorr, which is about an alien invasion that seeks to totally conquer human kind and use us for a food supply, and what humans do to stop it. The Voyage of the Star Wolf is about humans in space, and follows the adventures of a particular space ship.
