If you get a chance, check out page 22 of the April 2009 issue of The Writer magazine. In the From The Writer Archive (March 1969), author Lois Duncan gives great advice for breaking writer’s block. I found it especially helpful, since the rough draft of a novel (of which I’m about 3/4 done) is bogged down by writer’s block.
My two favorite Duncan books are Summer of Fear and the very-underrated Killing Mr. Griffin. Ms. Duncan, if you’re reading this, I think your depiction of humorless, no-nonsense teacher was absolutely brilliant.
