This app has no editors, the books offer the first 5 chapters free (that's how they get you), have very poor grammar, terrible spelling and very limited vocabulary. For $19.99 you get 2000 coins, to unlock a chapter you pay price that quickly goes up to 36, 37 or 42 coins. A book has between 62- 180 chapters. So if you start a book that's not finished yet you can easily pay $25- $70 per book for poorly written book. It's a rip- off. I hope you read this before you spend money.
