Which writing book should I read this month?

This year, one of my professional goals is to read two books about writing--cover to cover, none of this eyes-half-closed, skipping-around-chicken-reading that I often do with writing books. Why skip around? Well, some bore me, others offend me (I have issues with being told what to do), and most terrify me: they convince me that what I'm doing is Entirely Wrong And Must Be Fixed Immediately.

But then there are others that I love and that have inspired me, which is why I want to make a point of trying to find more great writing books. My "top four" list is below. What new ones do you suggest?

BIRD BY BIRD (Anne Lamott)

WRITE AWAY (Elizabeth George)

ON WRITING (Stephen King)

HOW TO WRITE KILLER FICTION (Carolyn Wheat)
