The Deluxe Transitive Vampire: A Handbook of Grammar for the Innocent, the Eager and the Doomed by Karen Elizabeth Gordon
I think you can even get a pdf version.
She has written a few other books too, and I'd also highly suggest:
The New Well Tempered Sentence: A Punctuation Handbook for the Innocent, the Eager, and the Doomed
They are unlike any grammar books you've ever read.
