Today (and told only, I think), you can download the free (and legal) eBook of Dreaming Anastasia by Joy Preble. This is happening because the sequel, Haunted is released today! I've heard it's a an amazing read so I'd recommend you download it for the future :)
You can buy it at Amazon US, at Amazon UK, or at Barnes and Nobles.
And don't forget to pick up a copy of Haunted as well!
