as I have written many stories I have found that they always end the way the I want them too.... this story however is really different. As some of you know, I was hoping for this novel to be shorter than what it has turned out to be. When I started writing it, I never thought about the warfare, demons, angels, and devils within my characters had to deal with throughout. It has led me on an incredible journey of writing my first Christian Fantasy allowing me to broaden my horizons, get out of my comfort zones, and learn some valuable life lessons.

But what about the end? The end of a story is suppose to be one that intrigues the reader that what's to find out what happens next. I had a really good idea on how the story is to end, and it is happening that way, but writing it has had its unexpected turns. I was kind of surprised really on how I am writing it...not at all what I had I mind about going at it. But that's what happens when you write for the Lord and not for yourself.
He takes and puts things in the story that I know it is him that he wanted me to write it. He flows all over the keyboard through my thoughts and heart as well as I immerse myself in this story. So when you write a story, think about who you are writing it for. God can take you on unexpected trails as you write, especially the ending.

I wont tell you how it ends, that you will have to read for yourself, and find out. but I will tell you this how the end happened was not how I expected it to happen...but it ended up happening the way I wanted it to. Hope this makes sense, I hope I didn't confuse you.

It's a good idea for a book in a series to have an ending that leaves the reader wanting to know what happens next. But for me, the most important thing about an ending is that it be satisfying, resolving the major threads of the novel cleanly and marking a definite end to this story. If an book tries to be "intriguing" in its ending, I think it's as likely to backfire and make me not want to read anything else by that author.

Thank you kingjon, that helps a lot

Yeah. Even if it's in a series, I think there needs to be some sense of closure, even if the closure is somewhat eclipsed by everything being set up for the next book. Course, cliff-hangers like The Empire Strikes Back or Catching Fire are also acceptable, but even then, in both those stories progress has been made, and it still ends with some closure.

Yes. In mid-series, you can still be starting new threads near the end of a novel, so long as you've tied off (or made progress that is substantial enough for the reader to feel vicarious satisfaction) the main thread(s) that that book is specifically concerned with.

Also note that if a book is a single volume of a multi-volume novel (like any volume of The Lord of the Rings or either of the first two volumes of Lois McMaster Bujold's Sharing Knife series), many of the same principles apply (the reader needs to feel some satisfaction and closure at the end, especially in re the issues that this volume has primarily focused on), but the pacing is very different.
