…do any of the following in picture book nonfiction:
1. Begin at the beginning.
2. End at the ending.
3. Cover everything in the middle.
I’m not being facetious here. Comprehensive coverage of any subject (particularly a biography) is not a wise goal for a 32- to 38-page picture book. It’s not possible, and you’ll invariable cut corners on good storytelling if you do, so don’t.
There. You’re free now. Go tell stories with facts.
