The Scene Book by Sandra Scofield

The Scene Book has some great food for thought, solving some problem stories through its organizing of narrative--

1. Beginning
2. Middle
   
3. End

-- and some additional components:

1. Event (built of beats)
2. Point/purpose
3. Emotional pulse
4. Focus (pivotal moment--bump to change from situation to situation)

It may be worth investigating if you've got a problem narrative.
