Without arguing for or against it, I'll just say it's the first book JGC recommends in his linked post. :)

I'm just going to fess up and say that I didn't read the linked post, just the comments.

We all do it sometimes, and it's no big deal. I just couldn't pass up the smile.

This book is on my shelf. It's a thoughtful and practical approach to language and writing. The prose in the book is often winking at you as it reveals a principle.
