I wonder if people who give three star and lower ratings realize how much it makes an author wonder. I don't think readers on good reads or even amazon realize how greatly a few simple words helps us as writers to be better.
"***" tells me nothing.
"*** I thought the plot line was too obvious." Or "*** There were too many grammatical errors" or even "*** The story just wasn't my thing" are so much more helpful than "***".
So please, as an independent author, I beg you, if you read it and feel the need to *, **, ***, **** or even *****, drop a one or two sentence note telling us writers WHY you felt it was one star over another! It makes it so much better for me going into a new book, and really does allow me to grow.
You really have no idea just how insightful your musings are to me!
