I like to keep several copies of these two books in my office:
Dancers Among Us by Jordan Matter
Tiny Beautiful Things by Cheryl Strayed
One or the other is perfect for almost every person who visits me.
But now I have another.
And you should have it too:
Dreyer's English by Benjamin Dreyer
If you sling words for fun or profit, you need this book.
Sample: Only godless savages eschew the series comma.
Do you have "in-stock" books you keep to give to people? A go-to gift book?
