This story really hurts from how it is constantly hopping between different plotlines. Keeps on trying to raise tension, then blunders it all by changing scene to somewhere else entirely. And repeat. Both extremely rapidly inducing readers fatigue, and overall just hurting each plotline too, alongside any pacing.
The whole "war" vs "kidnapping" stuff is bad enough by itself, but then inside the "war" plotline there's like 3 or 4 concurrent ones currently (princess vs prince, helis vs wyverns, assault vs bait).
