"Classical Rhetoric for the Modern Student, Fourth Edition" by Edward P.J. Corbett and Robert J. Connors (1999)

It's a 500-page book about classical rhetoric, so I'll try to keep this brief. Maybe it's too late for you to become a stronger writer, but in the event your child shows a knack for words it might be a good idea to get this book on their radar. For some reason, I went through most of my life never once hearing about it, until it was referenced in an academic paper I was reading about advertising. Which means either the state of the humanities had been in decline for much longer than we thought, or narrow-minded parents were desperately dissuading their children away from writing as a career. I've found, if you dissuade a talented, budding writer away from a writing career, you're pretty much sentencing your peculiar, creative child to a long, sad, unfulfilled life (an unusually large number of these children grow up to be financially secure, emotionally damaged Asians.) So if you want to spare those kids a future, decades-long SSRI/Xanax dependency, just know this might actually be the best book on the nuts-and-bolts craft of writing I've ever read. (Sidenote: I can now recognize, thanks to this book, the advertising agency Fallon McElligott, in their heyday, more than anyone else, made use of classical rhetoric precepts in their work.) Five stars.
