The Letters that Never Came, by Mauricio Rosencof

(Las cartas que no llegaron) A rich evocation of life in a working-class neighborhood in Montevideo, Uruguay, in the mid-1930s, as seen through the eyes of Moishe, the child of Polish-Jewish immigrants. In what is a daily routine, Moishe's father waits for the postman at the window, always hoping for news of his family from the Old Country. Don Isaac's relatives are prisoners of the Nazis, so all he can read Moishe and his mother is letters from before. Interspersed among the child narrator's reminiscences are the letters those relatives might have written, bearing witness to their suffering. Letters that never came.

Book club member Flaurie Imberman writes, as an Amazon reader reviewer:

I read this book in the original Spanish a couple of years ago and was blown away. Rosencof creatively weaves together his own history with that of his ancestors who perished in Hitler's camps. I have not read this translated version, but it is probably excellent since it is part of a series that has included terrific books.
