What stars mean in my reviews

In March, I began reviewing books. My intention was never to become a full time book reviewer, but I wanted to share some of the books I read. So far, I've only reviewed books that I thought warranted 4 or 5 stars. This is because there seems to be a stigma against 3 star reviews (or God forbid, 2 and 1 star reviews). From what I've been reading in forums and on blogs, some authors freak out when someone gives their book a 3 star review. It's as if 3 stars means the book is horrible. Not so!...
