Almost as old as time itself is the question:
Should I outline my novel or just wing it?
Jon and Juliet suggest that the answer to this ancient mystery is: Yes!

Jon discusses his experience trying an outlining system described in Libby Hawker's Take Off Your Pants!: Outline Your Books for Faster, Better Writing. Amazon link.

Jon talks what worked, what didn't, and where he is now. Juliet offers the editorial perspective having seen both authors who were heavy outliners and others who wrote by the seat of their pants.
