Towards the beginning of the last chapter Allie remembers Noah for a little bit and before she forgets him again Noah wishes that they could die like this, remembering each other, dying as a married couple. I'm not sure if they died with Allie knowing who Noah is, but I love the way the book ends. He goes into her room late and night to watch her sleep because he misses her, and he kisses her and all of the sudden she kisses back and then she tells Noah that she misses him, and it's a miracle and the book ends.
