Scholastic has a great link to a list of books that you might enjoy if you loved The Hunger Games like I did. You should check it out if you're looking for more. You can also read excerpts from each book on Scholastic's website.
Out of that list, the one that I added to my to-read list is:
Here is a blurb from Goodreads:
Gemma, 16, is on layover at Bangkok Airport, en route with her parents to a vacation in Vietnam. She steps away for just a second, to get a cup of coffee. Ty - rugged, tan, too old, oddly familiar - pays for Gemma's drink. And drugs it. They talk. Their hands touch. And before Gemma knows what's happening, Ty takes her. Steals her away. The unknowing object of a long obsession, Gemma has been kidnapped by her stalker and brought to the desolate Australian Outback.
Stolen is her gripping story of survival, of how she has to come to terms with her living nightmare - or die trying to fight it.
Lately, I keep reading books that are so dark, but yet so good. I think it's time for a more "happy" book. :) Any recommendations?
