Grammatically correct

the long version

"Filled with self-test exercises and whimsical literary quotations, Grammatically Correct steers clear of academic stuffiness, focusing instead on practical strategies and intuitive explanations. Discussions are designed to get to the heart of a concept and provide a sufficient sense of when and how to use it, along with examples that show what ambiguities or misinterpretations might result if the rules are not followed. In cases where there is more than one acceptable way to do something, the approach is not to prescribe one over another but simply to describe the options."--Publisher's website.
