Sophia Shalmiyev wields her intellect and insight during a conversation about her lyrical, heart-breaking memoir, “Mother Winter.” Both the book and the conversation are a collection of Shalmiyev’s influences, from traumatic moments of her early years in Leningrad to the inspiring Riot Grrrl feminist movement. Shalmiyev speaks with authority and passion about mother loss, inviting listeners into a kaleidoscopic take on the immigrant narrative while offering possibilities for a more just future.
