Very good. I was slightly put off by the way we jumped right into large and complicated sentences, but it worked. After the first study, I really got into the flow and enjoyed myself. The cases studies were explained well and many of the examples were very funny, especially the Faulty and Funky Parallels.

In addition to entertaining, the book instructs. It provides useful tips on writing better. Casagrande's central thesis is that writers should (mostly) write to serve the Reader. Each of the sentence tuneups show to meet the Reader's needs over our own.

I have only two complaints. Early on, the phrase "begs the question" is used where "raises the question" is meant. That's one of my pet peeves. More seriously, in the chapter on unclear antecedents, the phrase "call it a variation on AA members' belief that helping others helps them stay sober" contains an unclear antecedent. Who is them, the AA members, or the others that are helped? These complaints are relatively minor, an did not appreciably lessen my enjoyment of the book.

I recommend It Was the Best of Sentences to anyone who writes, or enjoys writing.
