For centuries, mariners spun tales of rogue waves over one hundred feet high and scientists dismissed them. Then a British research vessel was trapped in a vortex of mammoth waves. As scientists scramble to understand these destructive monsters, others fly around the world in search of them. Susan Casey juxtaposes the exploits of Laird Hamilton and his fellow extreme surfers against scientists' urgent efforts to understand the annihilating power of waves. (Bestseller)
