In a world increasingly dominated by xenophobia and wall-building, this month we wanted to look to the books that cross borders instead. So our theme for this show is migration in literature, from the novels of John Steinbeck to Zadie Smith. We've been wanting to talk about this for a while, and we waited for the perfect author guest to explore this with us. We spoke to award-winning Mexican author Valeria Luiselli, whose latest novel Lost Children Archive is about both a road trip one family takes across America, and child migrants on the US/Mexico border. So, come and tear down walls with us for the next hour on Literary Friction.
