I am often surprised when reading Kindle books about how poor the editing is. It’s harder to show gaps and page breaks. So sometimes I read one sentence and the next sentence is a completely different scene. In a hardcopy book, there would have been some gap, some marker of the transition, but in the Kindle, this is often not visible, and I am literally shocked in the story to move back and reread the last page to figure out what happened.
Also, punctuation is often messed up in Kindle books. I find additional commas and periods where they should not be, sometimes capitalization is messed up. Come on, Amazon, run a Word grammar checker on your copy at a minimum and most of this stuff would be found – BEFORE you make us all pay $10 for this content.
Since I am not getting the hardcopy book anymore, the least I can expect is that you edit the content properly before you release it.
