Esther Safran Foer’s mother died in 2018, a greatly-loved great-grandmother, yet one who refused to speak about her life in wartime Lithuania. Safran Foer’s I Want You to Know We Are Still Here (HQ, £16.99; Tablet price, £15.29) is written “to keep the stories alive”. Her search takes her from Washington DC to the site of shtetls in Lithuania where many of her family were murdered. She uncovers thickets of family connections, and comes to see herself as “a hinge between generations”. This is a profoundly moving book, an act of remembrance, a kaddish.
