Is there anything new that fiction writers can tell us about the Holocaust?

You would think that there would be nothing new that fiction could tell us about the Holocaust, with virtually all survivors and witnesses gone - though a few books in the past few years have surfaced or resurfaced (Suite Francaise and the novels by that Dutch writer, Keilson) and you could even add the recently rediscovered novel of German resistance, Every Man Dies Alone - but honestly what more can be said? - one would think - but then something comes along and we realize that great writers are always imagining new ways of thinking about our world and in fact eras of trauma and conflict will have resonance and ramifications in our thoughts and imaginations long after they have faded from memory into history - that's what I'm thinking after reading Anthony Doerr's really odd and compelling story Afterworlds, in his collection "Memory Wall," about an 80ish woman living in Ohio near Lake Erie (has Doerr ever written two stories with the same setting? is he ever at home?) who was in a Jewish orphanage girls' in Hamburg through the war and, through the actions of a benevolent rescuer, was the only girl not sent off to the death camps - and now nearing the end of her life she has strange and fragmented memories of her childhood. Doerr stories are - at least in this collection - all composed of short segments, or fragments, which at times can be an affectation but in this story a very useful and deliberate structure and technique in that the fragments aptly represent the way she is thinking - broken bits of memory that barely cohere - and they introduce us into her consciousness, one of the true and rare accomplishments of a good writer. As a counterpoint, her grandson, a college student working on a paper about the war, cares for her and helps to draw out the shattered pieces of her memory. Strong concluding story to an excellent collection.
