Popular Twilight author Stephenie Meyer said on her website her next book "The Short Second Life of Bree Tanner" will be available as both a physical book and online.

The book will be available for purchase in bookstores on Saturday, June 5 in hardcover for $13.99 and free online starting at noon on June 7 until July 5 at www.breetanner.com.

"I'm as surprised as anyone about this novella," said Meyer. "When I began working on it in 2005, it was simply an exercise to help me examine the other side of Eclipse, which I was editing at the time."

"I thought it might end up as a short story that I could include on my website. Then, when work started on The Twilight Saga: The Official Guide, I thought the Guide would be a good fit for my Bree story. However, the story grew longer than I anticipated, until it was too long to fit into the Guide."

Meyer said she wanted to give the book away for free online as a special gift to her fans. "I'd always considered The Short Second Life of Bree Tanner as something for the fans," said Meyer. "They have been so supportive of all things Twilight."

One dollar for each book sold in the U.S. will be donated to the American Red Cross. Those who access the book online will be asked to a make a donation to the charity.

"I have been moved by the generous outpouring of support for the recent crises in Haiti and Chile," said Meyer. "I am glad that sales of this book will support the American Red Cross with their amazing efforts abroad."
