Buck is abducted from a comfortable life as a pet and tossed into the maelstrom of the Yukon Gold Rush and the brutal realities of frontier life. Buck changes hands a number of times before landing in the kindly hands of John Thornton, a brief respite before the storys final turn.
The plot concerns a previously domesticated dog named Buck, whose primordial instincts return after a series of events leads to his serving as a sled dog in the Yukon during the 19th-century Klondike Gold Rush, in which sled dogs were bought at generous prices. Buck learns from his experiences and becomes an overall dominant (conquering), primordial (More like ancestors) beast (undomesticated). Buck also learns lessons and remembers instincts (from his ancestors) that help him to become a ferocious beast.
Published in 1903, The Call of the Wild is Londons most read book, and it is generally considered his best, the masterpiece of his so-called early period. Because the protagonist is a dog, it is sometimes classified as a juvenile novel, but it is dark in tone and contains numerous scenes of cruelty and violence. The Yeehat, a group of Alaska Natives portrayed in Call of the Wild, were a figment of Londons imagination.
