Best overall book on the craft

I have an extensive library, much of it in digital form, on the craft of writing, publishing, marketing etc. My son has requested a book on the basics of writing a novel, for himself as well as helping to teach his children. They homeschool and a couple of them already have started writing. This makes my grandma heart happy, I admit.

I’m looking for others’ suggestions on the best overall best book for covering the basics in one complete volume. I love K.M. Weiland’s books, but so many are e books.

Thanks for any help
