Hi, my name is Emma Lai, and I'm a recovering panster. I used to write by the seat of my pants. My characters dragged me this way and that. It was like a rollercoaster ride. The peaks were moments when my fingers flew over the keyboard racing to keep up with my characters. The valleys were times when I was stuck trying to recapture the momentum of the peaks. Both His Ship, Her Fantasy; His Hope, Her Salvation and Twice is Not Enough (coming soon from The Wild Rose Press) were written in this manner.
What happened? As always, life. Create a series and suddenly there's the issue of overarcing plot. That requires tracking. Create a baby and suddenly your spare time becomes used for things like showers and food.
That ever precious commodity of time leads to the requirement of plotting. I don't have time to let my characters drag me this way and that, but I do have time to catch the essence of the journey. A few lines to spur my memory and the story can progress in my head, if not on paper.
But, if I had my way, I'd still be a panster. :)
