Song of a Blackbird by Maria van Lieshout
This graphic novel is based on real historical events, but has fictional people inspired by real ones. There are two timelines in the book. In the present day, Annick is researching her grandmother's past to try to find biological family members after her grandmother's health situation led to discovery that her grandmother was adopted by the family she grew up in. There are five prints on the wall of her home that are clues to the past. Each of the prints takes us to a building that played a role in the Nazi deportations of Jewish people in the Netherlands and the resistance that worked to save lives. We quickly learn that Annick's grandmother had an older brother that was also spirited away from his Nazi captors, but the two were separated, and never reunited. He thought she was dead, and she was young enough at the time not to realize that she had lost him.
Using the prints as clues is an interesting plot device that also takes us to printers that created false documents for the resistance, and even to an historic bank robbery that I hadn't known about before reading this.
The limited palette works well here, and the blackbird in the title serves as both a narrator and a symbol of hope that helped people survive.
