This is a love story taking place in the past and the present.
Although the narrator is in the present, most of the action of the story takes place in 1946 as a flashback. An old man named Noah is reading to an old woman. Noah is poor, and Allie is rich. Noah is in love with Allie, but they are separated and he sends her one letter a month but she does not respond. Noah inherits a fortune, but regrets that Allie has not returned any of his letters. She has not received any. Noah has returned to his hometown, and bought an old plantation to restore.
He was thirty-one now, not too old, but old enough to be lonely. He hadn’t dated since he’d been back here, hadn’t met anyone who remotely interested him. (ch 2)
Noah runs into Allie, and she seems to still love him. Back in the present, Allie has Alzheimer’s and no longer remembers who he is, even as he reads her their story.
