It’s a bad habit sign the final conflict of the story is resolved, always, by the raw power of the protagonist. Add that together with the protagonist being pretty bad at their job, failing at every turn to nail down the mystery of the story. Frankly, I think the “good guys” are just dumb at this point. The prior story was filled with “Me rar smash don’t care about mysteries!”. This one is all “Me no can capture anyone ever.” It caps off with the protagonist breaking established rules and having more power than everyone. This last is particularly frustrating because the proper solution would have been “even though the King is displaced, the heir is back at the big magic throne and can intervene, proving the value of the monarchy”. Apparently the heir is busy with his love life or something, because that’s about all we know about him. However, instead of a responsible monarchy following through on Chekov’s Super Throne, or a basic respect for delta-V, we get special protagonist powerz.
I’d avoided this series for a while, mainly because I suspected it would turn into this sort of drek. The first one seemed to circumscribe appropriate limits. The second was clearly a “pivot to series”. The third…I probably should have stopped there. I spent most of the fourth wondering why the guy supposed to be investigating stuff preferred to boom things up instead of ask questions about the mystery. Honestly, after the guy wallowing in a conspiracy in his own organization tells a couple hundred people he’s going to go get his last chance at a clue, I kinda put this in the “too dumb to live” category.
Also, anti-matter is stupidly energetic. The author should stop talking about conjuring GRAMS of antimatter into existence if he doesn’t know it’s like saying a 100 megaton bomb.
