Mother Tongues

My rating system: I begin with one star being equivalent to a rating of "C-". Progressing upwards, I add ½ star for each step, up to the maximum 5 stars, which is equivalent to a rating of "A"+. I reserve ½ star for BOMBS, there being no option of zero or negative stars. As a result, I set aside my rating space for good books, and don't squander half or more of that rating space on books that are of marginal quality.
