I heard about this site a few weeks ago and quickly signed up one of my books, No Good Deed. At the moment, they are free. What makes it different is that the site isn't about book price or even reviews. It's for those readers who really want to get a good idea of what a book is about. With ebooks, you can read the beginning, and read reviews, but you can't browse through the book and find a good scene to start reading mid-book. I know I used to find a lot of books that way. If I found an intense scene while thumbing through a book at a bookstore, I'd almost always buy it. This helps with that problem by including excerpts from beyond the first 10% that Amazon allows.
I asked for help from my readers about what scenes, besides the opening one would be most likely to grab a reader. I had several suggestions for the opening scene where Mark saves the baby from drowning in the bathtub, which makes me glad that it was the scene that hooked so many of my readers, but I decided on two that a reader couldn't find anywhere else except by buying the book. One scene is with Jessie and Jim, the other with Mark and Bill.
