You can read Stephenie Meyer's The Short Second Life of Bree Tanner for free on Breetanner.com, for a limited period:
"This site will be live from noon EST on June 7th until midnight EST on July 5th. Please keep in mind that you can only read the book here – you won’t be able to download it to your e-reader or phone. And you can’t print it out.
Some of my fellow UK bloggers have bought and reviewed it already, giving it the thumbs up:
Empire of Books
The Crooked Shelf.
