boys gymnastics children’s book?

MasterPuppeteer, “Proud Parent” of a 7-year-old male gymnast, is looking for a book about boys gymnastics.

It’s for a school project.

I can’t think of children’s book of that description.

She’d be happy with one with both a girl and a boy on the cover.

Leave a comment if you can think of one.

Or if you plan to write one.
