I'm an author. And I was wondering if you have ever wondered how addictive your book is? If 10 people read a random short paragraph of your book, how many people out of those 10 would continue reading?

Of course, part of this depends on the subject of the book. A book about sex may be more interesting to 10 random people than a book about a lost dragon in Japan.

I'm asking this because I have created a application that is able to hide money in books online. The application is able to put any amount of money inside books, either digital books or paperback books. So, I'm just thinking about how much leverage does this application have. Would it even be beneficial for this industry?

Any thoughts are appreciated. Thank you.
