1. You have to wait 6 hours to unlock a chapter unless you pay for an expensive subscription. 2. There is no way to tell if a book is completed or not so you spend weeks reading to find out the book is unfinished and you have no idea if or when there will be new chapters to continue the story. 3. Chapters are short. Very short, so you wait 6 hours for two to five minutes of reading. 4. Once you finish a book, there isn't a way to mark that you have read it. So overall, not worth it.
