When will Akatsuki no Yona (Yona of the Dawn) Come to a end?

It's gone on for almost 17 volumes, and it seems like the author is stalling on the storyline....

I personally think it's time for it to come to an end, cause there really needs something to jumpstart the story...

Dont get me wrong, i love the manga and the anime, but i think the curtain needs to fall on this one...

The question is, when?
