Particularly when we don't get to see justice. And there were so many in this book. It was 568 pages and there was really no forward movement on the story until around page 300. And even then the resolution was left to the last 20 pages. All those words and I didn't get to see anything I wanted to see, and yet she still shoved in that bit of ~it continues~ at the very end. Frankly, if you're writing a book about devil worship and are already at 568, why not go the extra 98 pages? That would have left a lot of room to have a more satisfying climax and wrap-up. At least I really liked the hero and heroine, though there were some things I could do without.
