First time I've read this in over a decade, I'd guess, and it's more amazing than I'd remembered. When I read this in college, it was a fantastic dystopia--but as an actual adult now, I have a better sense of the heartbreak and anguish of the Giver, and of Jonas's dawning understanding of his society. 
 It's also interesting to re-read this in light of having read Son recently, and even Messenger longer ago. I still think the series goes a little off the rails when the magic becomes such a big part of the story (it's in here, but subtle). 
 Overall, this holds up amazingly well.
