More rewriting!*! Do I have to?

As I flesh out my set-up, creating a fuller storyworld and building its inherent opposition to the main character and her family, I've been surprised that I'm also reconsidering the ending. I don't mean that it's not working. I love the ending. It's very powerful. Exciting, visual, emotional. Rather, I may have too much story and perhaps the novel Green Tara ends earlier than it has in previous drafts.

I'll digress. I've always imagined this story as the first part of a trilogy. Part I - Virginia finds her missing mom on the planet Green Tara. Together with her cousin, Gordy, they collect living ocean greens--the oxygenators, if you will. And when her dad tracks them down and reconnects, they all travel to Earth and replenish the dead ocean waters. Of course, the novel goes into 133 pages of detail for all this to happen.

I have sketched out Parts II and III in a similar general story arc, but I have yet to work them out in any detail. One thing at a time, right? . . . Maybe.

Back to the current rewrite of Part I: I'm taking more time to set up the nature of the controlling entity, the Triumvirate, in the beginning. And I'm reincorporating direct conflict via a pair of Triumvirate sentries in a scene that comes later in the story. I want to get these fixes done and get this story out the door.

But my instincts are saying, Don't rush it. Take the time in Part I to know the larger threat and to feel the dissonance of a family fraught with betrayal. End it with Virginia's family reunited, and leaving the lush sanctuary to begin the next phase of their journey. I can combine rescuing Gordy's mom and restoring Earth's oceans in Part II. (The other missing mom is, after all, hiding out in the Mars colony and has been waiting for the rest of the family for years.)

Am I dawdling on this one manuscript, just because I'm afraid to get it to publishers and to hear all their objections? Or have I found a more elegant way to divide the trilogy? The only way I'll know, is to outline Part II. And while I'm at it, outline Part III.

Ouch. Outlining's the toughest, makes-my-brain-hurt part of the process.

Do I have to?

I heard that George Lucas outlined all of the Star Wars saga before he made "Part IV" and that Jo K. Rowling outlined all seven of her novels before Harry made it big. If they're my muses, I must follow their lead.
