Jack London 
Daughter of the Snows [EPUB ebook] 

"A Daughter of the Snows" (1902) is Jack London’s first novel. Set in the Yukon, it tells the story of Frona Welse, "a Stanford graduate and physical Valkyrie", who takes to the trail after upsetting her wealthy father’s community by her forthright manner and befriending the town’s prostitute. She is also torn between love for two suitors: Gregory St Vincent, a local man who turns out to be cowardly and treacherous; and Vance Corliss, a Yale-trained mining engineer. (Wikipedia)
