I just re-read this book of Lois Lowry's in light of the Hunger Games trend, and I must say that this book is beautifully done. For more info, check out my review at Goodreads. (click the picture to read it)
Definitely worth it if you're looking to broaden your spiritual vision and to open yourself to new ideas. Will definitely change your relationship with "God" and cause you to question your brand of Faith. Not for the narrow-minded AT ALL.
