Jack London 
Children of the Frost [EPUB ebook] 

This collection of short stories shows the adventures and misadventures of the "children" alluded in the title: members of several Native-American tribes of the Canadian Arctic, Alaska and the Pacific Northwest at the turn of the XXth Century, on the backdrop of the Klondike Gold Rush amidst an harsh, unforgiving, Darwinian (red in tooth and claw indeed) Nature. The inevitable clash of civilisations brought by the coming of the gold-seeking "Sunlanders" often leads to tragedy of several degrees ranging from minor squabbles to all-out war and near annihilation.
