Lee Child

I write in the afternoon, from about 12 until 6 or 7. I use an upstairs room as my office. Once I get going I keep at it, and it usually takes about six months from the first blank screen until 'The End.'

The most fascinating powers don't mean a thing if the guy's poorly motivated or dull, and the most generic powers won't hurt a well-motivated character. Personality and motivation are what make Magneto, Magneto and not Cosmic Boy. The powers work for him, but it's his motivation that makes him the character he is.
