You download the epub off of Library Z or Libgen, and you airdrop it to their device. What you were doing isn't "buying" anything, Amazon has on more than one occasion deleted books off of devices after they had been purchased. On the subject of children's book, a few weeks ago I checked to see if there were retail versions of the old Choose Your Own Adventure books (there were, for Kindle!). Turns out, none of the "turn to page X" instructions are links, but also none of the pages have the original page numbers. $8/each, and you can't get a refund. The Amazon pages are full of 1-star reviews of people bitching about it.
