Chapters "strategiacally" missing during important moments in the story.
Chapters 33 - 40 are still missing.
They did a free week and provided 80 chapters but removed some chapters in between while uploading a few of them daily until the free week special ends.
Although the book claims to give you 80 chapters to read for free. You would only have read about 30 - 40 chapters. Unless you do not mind skipping bits of the story.
I think it's a horrible and misleading strategy which might end up hurting the book.
