A riveting and rollicking tour-de-force about the terrifying power of nature's most deadly phenomena — colossal waves — and the scientists and super surfers who are obsessed with them. The New York Times bestselling author of The Devil's Teeth probes the dramatic convergence of baffling gargantuan waves that pummel oil rigs and sink massive ships, the extreme surfers willing to stare down death in order to ride them, and the marine scientists trying to unlock the physics of these waves, the climate changes that are provoking them, and what chaos they might wreak. Susan Casey explores the phenomenon of monster waves and how they have become an obsession for extreme surfers like Laird Hamilton — who serves as the author's guide as she takes the reader into the intense, white-knuckle world of 100-foot waves.
