First was And Another Thing..., the sixth book of the Hitchhiker's Guide to the Galaxy trilogy, written by Eoin Colfer. It's not worth it. I'm not even sure that it would be worth it from the library. *Sigh*.
The second book was Groucho and Me by Groucho Marx. I grabbed it for readability and my interest in the topic. It truly is pretty well-written, and you can see Groucho's deft touch with the language.
