It's extremely expensive and frustrating. It's pay per chapter. I paid $8 and am less than halfway through my first novel. There are bonuses you can get for reading but are there some books that are free so I can collect those bonuses to finish a book I already paid so much for? If so I can't find them. Poor design. I started a book last night and couldn't find it this morning. The app just adds things to your library that you didnt choose and not the books that you already started.
