I panicked, wondering if there was enough story left to make up a whole other book. But as I thought about it that night (I usually lay awake late at night working out plots and story problems in my mind) and sat down and did a bunch of scene brainstorming and story development the next day, I realized that yes, there does have to be a sixth book, and there's plenty of story for two books instead of one. So a Book 6 there will be.
I think I've known, way deep down, for a long time that it would take another book to finish off the series properly. For a long time I had envisioned the events of Book 5, which moves the story from the frontier - the Wildings - into the civilized land of Granadaia, as being the climactic events of the series. But that just didn't seem right. The series is called Daughter of the Wildings, and it's about that uncivilized frontier land, its unique magic, and the connection between Lainie Banfrey (the Daughter in the series) and the land and its magic. Finishing it off in Granadaia without coming back to what is the heart of the series would be an unsatisfactory ending that doesn't fit with what the series is about. The more I thought about it, the more I realized that the events in Granadaia are the leadup to the climactic events, and not the actual climax themselves. The story has to come back to the Wildings, to the threats to the land and the people that have been building up through all the other books, and to the real significance of Lainie's unique power and her relationship to the land, and also integrate Silas fully into that relationship, in order to tie everything together and bring the story to a meaningful and satisfying conclusion.
As I thought this through, I thought that maybe the Granadaia part and the return to the Wildings part could just be two halves of the same book. But the more I developed the storyline, the more it became clear that the two halves of the book are also two totally different story lines, each with its own central story problem, instigating events, development, and conclusion. I aso realized that if the book was going to be an equivalent length with the previous books in the series, I was going to have to skim over or leave out a lot of important stuff, or else the book was going to be twice as long as the other books.
Therefore, the obvious answer, which waited for that brainless and bored moment of brushing my teeth to hit me upside the head, is to split "Book 5" into two books.
I think I'm about ready to start writing the last two books. As with the other books so far in the series, there's this feeling of jumping into the deep end without really knowing how deep the water is or what's waiting in there. I know where the books start, and where they end, and have a general idea of what happens in between, but very few of the details are clear. But so far it's worked out well, so I just have to make that leap of faith two more times. I think I'll just write straight through, without stopping between books 5 and 6, since I'd already been planning them as a single unit. With hard work and a minimum of interruptions, I hope to finish the drafts of both books by October.
So, yay! More time with Silas and Lainie! And none of this is even taking into consideration my idea for a possible follow-up series.
Note on the story blurbs for Daughter of the Wildings: All six are up. I apologize for any cheesiness, especially in the last few. Writing blurbs is hard, especially if you're trying not to give away any spoilers. And I want to stipulate that in my books, suggesting that the hero and heroine end up together is not a spoiler. In addition to being fantasy, my books are also romance, and to be a proper romance (as opposed to more general love story), you have to have the Happily (even if things aren't easy) Ever After. It's expected, as a hallmark of the genre. (Plus I hate unhappy endings.) The question isn't if they end up together, but how.
In the meantime, edits on The Lost Book of Anggird are progressing apace (I'm planning a blog post on the worst writing advice ever and how it nearly killed Lost Book), along with the first major revision of Sarya's Song. Maybe I'll do a post on that too, how I struggled with it for years, then applied some very helpful story-planning techniques, and now have the least-broken first draft I think I've ever written.
