A general memo to all authors:
You don't get to decide what readers write in their reviews, and you don't get to decide what readers need to know before picking up a book.
It's unlikely your book is so original that no one has ever written about the topic before. And there are readers who no doubt have legitimate reasons to not want to read about said topic (whatever the frell it is), no matter who wrote it.
So please, let readers do their thing.
