Few people have lived as many lives in one life as Jack London: hobo, sailor, journalist, autodidact, gold prospector, oyster pirate, world traveler, farmer, social activist, and the author of fifty books of fiction and nonfiction. And he crammed all this into 40 years. His great novels and stories, The Call of the Wild, The Sea Wolf, To Build a Fire, Before Adam, Martin Eden– these ignited my imagination and sowed the seeds of my wanderlust. There would certainly be no Feral Trek without Jack London.
