Louise Kennedy (author of an acclaimed novel, Trespasses) writes beautifully about the Irish and their tumultuous inner lives. In the story, “Hunter-Gatherers,” Siobhán’s fascination with a hare in her backyard turns sour when her lover Sid abruptly puts an end to the wild creature’s life. “In Silhouette” traces a line from the present-day Irish countryside to the Troubles of the 1980s.
