Clean Stars-- What does that mean?

I love to read, however, I hate when I get into a book, I'm invested and then there's a certain scene added or a certain word added making the book not-so clean.

When I watch a movie, I also like it clean, but movies have ratings. I watch PG and most PG-13. I stay away from anything R or above, because that rating tells me there are thing in the book that I don't want in my life. I so wish books had ratings!

So, the books reviewed on my author blog, jenatkinsonwrites.blogspot.com, will all be PG or PG-13. If a book were to get to R status I would stop reading and, therefore, not review it. 

There ya go! That's what it means when I offer clean stars!
What merits a clean star to come...
