Lois Lowry’s Messenger takes place a few years after the events of The Giver and Gathering Blue. Jonas has settled down in the seemingly genuine utopian village where Kira’s blind father, Christopher, found refuge. Jonas has become the village Leader, with the simple and descriptive name of Leader, and Christopher has become the village Seer, with, ditto. Matty is still Matty, if a little cleaner and more educated, now hoping to earn the name of Messenger. We also get a hint that just maybe the community of The Giver has been forced to change, just a little, by Jonas’ departure, and that they are willing to forgive and forget.
(That’s Jonas’ interpretation. My interpretation is that the community is still so against change that they are doing everything they can do to ensure that no one in the community knows that alternatives exist—even though alternatives are clearly around.)
