BILL STREEVER, a biologist and affiliate faculty member with the University of Alaska, Fairbanks, is the award winning and bestselling nature writer behind Cold , Heat, and And Soon I Heard a Roaring Wind. He has worked on issues ranging from the environmental effects of underwater sound to the evolution of cave crayfish to the restoration of tundra wetlands to climate change. With his wife, marine biologist Lisanne Aerts, he lives aboard the cruising sailboat Rocinante, currently in Central America.  When he is not busy fixing the boat, he spends his time sailing, diving, hiking, rowing a dinghy, paddling a kayak, seeing the world through the twin lenses of science and history, and, of course, writing.
