Only reason it gets a star is because the books are good. But they want way too much for these books. They charge you for every chapter. And they make them short just to keep getting money out of you. I'm on chapter 34 and am only 10% done with the book! Paid $5 once and only got me 10% of the book. Just ridiculous. I'm not paying over $10 for an electronic book. My advice find another app. There are much better and cheaper apps. It's a shame because I did really like the book
