This is an unusual one. It’s a grammar book, but it’s written in a narrative style. And just look at that cover.
To give you a flavour of the book, here’s a little passage:
“You see, a noun is a word that – ”
Just then my body froze because a truly enormous, hairy spider was crawling up the table leg. I let out a scream that must have been heard for miles around. Tarzan was momentarily startled, but when he spotted the creature he grabbed a knife and slit the thing in half. Then he carried both halves outside.
When he came back in and sat down I seemed to be breathing normally again, so I continued, “Basically a noun is a word that names something. It can name a person, place, an idea, or an action”.
