I am actually crying having just finished this. One of the best, funniest and truly cleverest books I’ve read in a while. Generally, Scalzi’s books are always funny and well-written, and this is absolutely no exception. I laughed out loud many times, and the characters were wonderful to read about. The situation is so silly, and the writing is so sharp, especially with its dialogue, that I can easily picture this presented in film form. If this ever happened and it’s just like the book, it may become one of my favorite things. As it stands, I’m being extremely effusive about a book I’ve already established I genuinely loved and am basically just talking in circles because it keeps me in the world of Starter Villain a little longer. Thank you, John Scalzi. Your work continues to make me so happy. Even if my cat doesn’t buy me a pub. 
(If the dedication didn’t give it away, it’s obvious this book is written by someone who has lived with—and loved—cats. The cat-person life insights are so on the nose.)
