Sara Wheeler with Simon Winchester

In Terra Incognita, Sara Wheeler revealed Antarctica. She does the same to the opposite pole in The Magnetic North, making known--in a combination of travel memoir, history and science journalism, all rendered in lucid prose--the faraway & fast-changing land to the north. As she travels through territories belonging to Russia, the United States, Canada, Denmark, Norway, and Findland, she documents a landscape hurt by pollution and crucial to our planet's health.  Wheeler will be talking to Simon Winchester, author of Atlantic.
