I didn't get on with this book at all. There was some helpful information about grammar and punctuation hidden among the random anecdotes, which just barely saved it from being a one-star or DNF. Overall, though, I think this book was written specifically for New Yorker mega-fans who would be thrilled by the name-dropping and insider gossip.

The author also:
-Mentions the ethnicity of her two Black coworkers (but no-one else) in her first ever job, then jokes that she was glad they decided not to come to her Halloween party because one of her other friends came dressed as a Klansman;
-Likens the question mark to "a lazy Irishman";
-Says a landmark was named after "an Indian chief";
-Proudly talks about how frequently she sneers at people who she thought were mispronouncing words, only to find out later that she was the one who had it wrong.

There's also a horribly problematic section about her sister's transition.

There are far better guides to grammar and punctuation out there that provide better information without all the baggage.
