Volume 17 is coming out August 18th. The title is Kurumi Ragnarok
Here's a short summary from amazon that I tried to salvage.
Well――let us begin the all-out war (date)
“I will speak all, now. No――everything that has happened so far.”
Kurumi, having saved Shido’s life numerous times, revealed the truth about the Spirits. When confronting his own closed memory of the past, <Ratatoskr> and the DEM's full-scale war begins!
Quote: The real Kurumi or a clone?
The real one, and just when she was allowing herself to be saved. It is unlikely Kurumi is meant to survive the whole ordeal because she has become such a rogue element.
Quote: And now she is fine?
No, she is on the verge of death
Oh, please, anon. Spare your question for next volume. I know you have plenty of questions, but all that can wait until the novel translation comes out.
Meanwhile, you can indulge the summaries here.
