This is kind of my feeling of this series, currently in chapter volume 5:
Basically i started out confused, who is this? Why dont we continue proper? Then it comes to "is that really? NO! What have you done?" and then i go "This is a mess, why do i even read this messy sequel to a good series?" and then chapter 5 came, and oh-boy here we are down on "Memento" (The movie) way of story telling where it almost goes backwards, and honestly its getting VERY interesting to see how shit went as bad as it did.
Its like a trainwreck you cannot stop looking at, only to be surprised how much of it seems planned. Its confusing sure, the author tried a new way to tell the story and it shows, but it does go somewhere...eventually.
