I was surprised the other day by a message in my inbox from someone who had used the contact form you see to your right to tell me they'd like to review my books. I wanted to be flattered, but when I took a look at their website, I observed that they are willing to review books for those who are willing to pay them $99.
Amazon expressly prohibits paid reviews, a good policy that protects authors and readers alike. Nobody likes to be scammed. When I launched my authoring career, I expected come-ons like this, so I didn't get upset about it. I'm just serving notice here that I was not born yesterday.
