Jack London 
Smoke Bellew 

Christopher Bellew is a success in the eyes of the world, engaged with the San Francisco paper and penning stories daily… but for no pay. When Klondike fever strikes the region, he sees his chance to break from drudgery — starting him on a journey that takes him over mountain passes and down swirling rapids, removing him forever from the world he knew and the man he was. Taking the name "Smoke, " he learns to thrive and flourish in the wilds of the frontier. (Goodreads)
