Basically, they'll charge you 0.15 USD / Mb if you opt for the 70% royalty. Or nothing, if you opt for the 35% royalty. The deal would sort of make sense if it weren't for because they put so little value on the table.
There's a funny thing going on with maps in books.
Fantasy novels frequently include maps, and some people are pretty vocal about how much they appreciate those maps. But the maps are never relevant to the story at all; you'd lose absolutely nothing by leaving them out of the book.
History books also tend to include maps. The maps are much less detailed, and it's rare for people to make appreciative comments. But the maps are in there, even though the authors appear not to really care for them, because they're necessary to understanding most of what's going on. As far as relevance to the text is concerned, history books have a much more severe undersupply of maps than fantasy novels have an oversupply, and the fantasy oversupply is considerable.
And yet, somehow, all of the popular demand is for fantasy novels to have more maps and for history books to have fewer.
Totally fine.
> nor does he hold himself accountable to them.
Iffy: consistency matters in worldbuilding.
> Fans trying to stitch his world together run into issues and he just straight up doesnt give a shit.
Bad: This implies that 1. the constructed world is inconsistent and 2. the author doesn't care. A story set in a fluid world where things just move around breaks immersion and undermines stakes because the reader doesn't know what the rules are and stops caring when it becomes clear that things are just made up on the fly whenever it's convenient.
It's a different story on physical media, for example a well-made hard cover.
- They keep at least 30% of the cut, but much more if you dare to include high quality images in your e-books. That map you spend a week or two creating? It'll be a messy blur in a kindle.
- If you are not a best-seller, Amazon brings you nothing in terms of discoverability. In fact:
- the moment a potential reader lands on your book's page, Amazon will show them ads for other books. Consider that that potential reader may have come there after you paid for ads in Amazon or in some other platform, or after you spent a day doing in-person marketing at an arts fair. That's just asinine.
The discoverability issue affects me the most as a reader, since Amz keeps surfacing ten-a-dime stories that happen somewhere in USA, mention starwars three times per page, and involve werewolves.
