First off, thank you for getting my book (and reading it lol). Secondly, OMG you're so right! It's the niche. "Money" does not do well for me on Amazon and people like the Publisher Rocket guy absolutely do find keywords and then supersaturate the crap out of a niche. You're SOOO right and it kills me because when it comes to writing another book I feel stuck. I want to write another book in the same niche but I know it won't do as well as I'd like simply because as you said, money topics don't do well on Amazon.
