An excellent piece by Nichole Bernier on the role of the paperback, talking cover changes and the like, at the Millions: "Here’s what I learned, after a month of talking to editors, literary agents, publishers, and other authors: A paperback isn’t just a cheaper version of the book anymore. It’s a makeover. A facelift. And for some, a second shot."
Michael Grant offers some typically wry advice for writers at the Guardian. Snippet: "Writers often offer up helpful hints, and I've done the same in moments of weakness, but here's the truth as I see it from my own narrow and subjective perch: You can either come up with stories or you can't. You either have the ambition and work ethic to sit there typing for months on end or not. But you do it by doing it." (On his second piece of advice, of course, I disagree, because I come from the proud school of Read Everything.)
