Lois McMaster Bujold est en interview sur ce site.

Petit extrait :
"Do your characters ever write themselves?
Lois McMaster Bujold : Almost all of them do, I think, bar a few spear carriers or others who just pop in long enough to deliver their portion of plot. (And even they have the potential of growing into full-blooded people later on.) But all the viewpoint characters certainly wrap their stories around themselves. I have on occasion started a tale with a plot, setting, historical event, or even a piece of technology as a seed crystal, but no story gets up and runs till the characters arrive. Of course I still need a setting, a place for them to act, and a plot, actions for them to take (and thus develop and display yet more of their character), before words can start happening. It's the old "three-legged stool" problem; the most immediately important leg will always be the one that is missing.

My characters also have the ability to go on a sort of sit-down strike, when what I have proposed that they do next isn't right. It's rather the opposite of what people mean by "the characters ran away with the story." I've learned to recognize it (not always right away) as a creative sort of writer's block, one that keeps me from wasting time and energy writing the wrong things. For which I thank them. I think."
