Until this hit's shelves
The Evolution of Mara Dyer.
I've been dying for this book and cannot wait to read it! I've just re-read The Unbecoming of Mara Dyer just because I loved it so much, and am so eager to read Evolution.
Michelle Hodkin has an amazing giveaway happening on her blog right now, only until Monday night though! And if you're lucky enough to be in the areas where she will be, I'd suggest going to see her. She's definitely someone worth seeing I bet. (She's even made it on my list of people, dead or alive, that I want to have dinner with before dying!)
