When the world-famous author Rebecca Solnit was about launch her book Wanderlust on audio, the Swedish publisher Daidalos decided not just to launch another audio audio book. Wanderlust explores the history of walking and the relationship between thinking and walking. To really put this insight to the test for real we released it with one reservation. You had to walk to listen to it. If you stopped, the book stopped. If you went to fast, the book stopped. If you’re where a train? No. You simply had to walk to listen to it.
