Query: You fill in the blanks

I did not like this book as much as the first two in the series. However, art is not always supposed to cheer us up. I think that Lowry is the kind of author who really wants the reader to become the storyteller and fill in the blanks. There is no neat package at the end, even in the book which is the third of the trilogy. Matty's true name communicates what I believe to be Lowry's central message. I don't want to spoil the end, so I won't reveal his true name, but the following quote is similarly revealing, and my favorite of the book. "So you could meet in the middle with your gifts? It wouldn't be so hard if you only went half way. If you met." Despite the abrupt ending, Messenger is a must read for those who have read The Giver and Gathering Blue.
