Create children's books on topics that they will need in the future. Example title: What Is Money?

I've written a book on basic economics for kids, Cost Benefit Jr., and the next book for kids I'm planning to write will be on currency, inflation, central banks, etc.

Now I'm wondering how I can utilize the book I've already written into the Steemit market?
