The Wave. Water waves. Not lazy surf lapping at your toes along the beach. Colossal, ship-swallowing rogue waves; scientists scrambling to understand the phenomenon; and extreme surfers seeking the ultimate challenge. Susan Casey’s account follows the exploits of boarders conquering suicidally large, 70- and 80-foot waves and the physicists trying to grapple with the destructive powers of 1,740-foot waves off the coast of Alaska and tsunamis in the Pacific. Casey is our guest.
