As the title says, I finished reading volume 4 yesterday, which means that I'm finally at the halfway point of the series (not counting the additional stories). I'm not gonna give my full thoughts on the book, which is something I'd like doing once I'm finished, but I'll just say that my current feelings are a bit mixed.
Volume 5 is technically the beginning of the second half of the book, but I'm aware that volumes 6 through 8 are extremely short in comparison. This means that, in reality, I should be well over the halfway point in the story. I believe that things might start getting interesting, now that Klein has reached demigod status, and that all the big secrets are gonna be revealed bit by bit. I also wanna see what's up with Amon, since apparently he's the main villain, but he's been doing basically nothing (to the reader's eyes) for 4 volumes.
It should be without saying, but I've seen how this community is with spoilers. I still have plenty left to read, so don't spoil anything if you're gonna comment.
