As she explains on her site she never intended for this to be published as a stand alone book.
The release of this book would be much different from any other she has released writing,
The Short Second Life of Bree Tanner
One other aspect of this release is the plan to give a more important gift to people who really need it. One dollar of each book purchased in the US from the first printing will be donated to the American Red Cross for their relief efforts in Haiti and Chile and other parts of the world where people are in great need. We're going to have an option online as well, so you can choose to make a donation if you want when you read the story online. I hope you will. I think that we can really help a lot of people with this.
We can only imagine it will be a great read. The new book is 192 pages and will be available on shelves June 5th.
