Elite cave diver Jill Heinerth joins on this week’s podcast to discuss her vivid new memoir, Into the Planet. It’s a deep dive into the formative experiences that taught her to face and harness fear, enabling her to build a remarkable career that has taken her to the literal ends of the earth. Heinerth shares the narrative arc of a dive, what it’s like to explore places on earth less traveled than the face of the moon, and the responsibilities that come along with being the Royal Canadian Geographical Society’s first-ever Explorer in Residence. Then our editors join with their reading recommendations for the week, including books by Shannon Hale (ill. LeUyen Pham), Rainbow Rowell, Ian Urbina, and Bruce Holsinger.
