A reasonably-satisfying conclusion to The Giver quartet, which I'm now curious to re-read to see if I notice Claire in the background--I'm curious as to how long Lowry has had this in the works, mentally. 
 Tagging this as Adult because, really, the writing is accessible to kids and teens, but the subject matter--well, I don't think they're going to have a lot of real understanding about the loss of a child and the maternal instincts that really propel the plot. This is a book for the adults who read The Giver 20 years ago (yeah, it's been just about 20 years; can you believe that?) as kids and want to know what became of the characters, and are now interested in the adult concerns that Claire (and Jonas and Gathering Blue's Kira) have. 
 What didn't work for me (minor spoilers if you haven't read the rest of the series): 
 (view spoiler)[Most of the book, I enjoyed, but as with Messenger the supernatural elements didn't work for me. Jonas is said to have a gift where he can "see beyond," and that's what makes him become the Keeper of Memories, but I was always able to take that as metaphor. Kira's gift for weaving, I was able to believe the same way. But then we get to Messenger and there's the Trademaster with his Needful Things trades and Jonas's "seeing beyond" is a weird sort of astral projection, and Gabe can do similar things... I dunno. To me, the fantastic elements really took away from the power of the book. (hide spoiler)] 
 Anyway, a good conclusion to a teen series with very little teen appeal these days. Sigh.
