Janis Bell: Clean, Well-Lighted Sentences

I love this little book. In addition to being clear and concise, Janis Bell’s grammar guide focuses on common mistakes I still make. In each explanation and each example, she writes as if she had read my mind. What I have found most effective is the way she teaches us to remember certain conventions such as when to use who and whom or lie and lay. It’s a must-have grammar reference.
