Centred on a community of immigrants precariously balanced on the edge of poverty in 1990s New York City, the stories that make up Sour Heart examine the ways that family and history can weigh us down, but also lift us up. From the young woman coming to terms with her grandmother's role in the Cultural Revolution, to the daughter struggling to understand where her family ends and she begins, these vibrant, raw and powerful stories introduce a bold and singular new voice.
