Harry Potter and the Old-Growth Forests -- apparently the Canadian edition of HP#6 is printed entirely on recycled paper, thus Greenpeace, the Sierra Club, et al. are urging a boycott of the American version. Hmmm, my copy says at the back it "contains no fibers from ancient forests," doesn't that count for something? Next time I'll go for the pirated e-version instead.
Incidentally, I finished the book on Tuesday morning, and it was brilliant. J.K.R. finessed the plot and tightened up the dialogue to near-Austenesque levels. I was laughing and gasping out loud at various parts...now I'm waiting for the other half of my "book club" to get it done already!
