I received an unsolicited offer from the "Distribution & Author Relations Department, American Book House" for my latest book, Confessions of a Reformed Financial Advisor (Yep, It's Mostly BS). Has anyone heard of them? I told them no, and they countered. I'm also getting lots of emails from the "I'm going to make you famous crowd, which I ignore. Currently, I'm on KDP and plan to use IngramSpark after I get an ISBN issue resolved. Any advice?
