Writing s novel is hella hard work. Especially when there are no guardrails, safety straps, or any other device that would help the writer have a faint clue as to what she is doing.
Larry Brooks, a story "fixer," has written three books on how to structure a novel (or screenplay) for maximum dramatic impact. Story Engineering, Story Physics, and Story Fix. All indispensable guides in structuring a story. We don't always see eye to eye, but I greatly respect his approach. Any aspiring writer would do well to pick up these invaluable guides. Find 'em on Amazon.
