This unique literary masterpiece opens in present-day France with Anne receiving a postcard naming four of her relatives who perished in the Holocaust. Who sent it--and why now? As Anne struggles to find out who these relatives were and what their lives were like, Berest blends mystery and history into an engrossing, propulsive weave of fictionalized genealogical narrative and commentary to explore the persistence of antisemitism through the generational trauma of one family and chart her protagonist's move toward embracing a religion and ethnicity she grew up knowing little about.
