Ever seen an endorsement for a book that reads something like this ...?
Read Sally's book! She's the bomb!
Read Bob's book! He's so great, and there's no way he wrote something bad!
I want to read BOOK by Katie because there's no way it's not as awesome as she is!
Here's the thing. I understand the reasoning behind such endorsements. If I am ever published, I plan the shill the hell out of myself, and enlist all my friends and family in the same. I suspect some of those endorsements will sound like, "Buy my friend Ru's book! She's so funny/has shiny hair/pays her taxes, you won't regret it."
On some level, that sort of positive word-of-mouth is inevitable.
But friends, being a good person does not mean you produced a good book. This goes back to my previous post about authors who think any criticism of their work is a criticism of them.
Good people write bad books. Bad people write good books. People who reject traditional notions of morality write good, bad, and mediocre books.
So let's save the Good Person = Good Book false equivalency for siblings and elderly relatives, ok?
