Abstract: Adventure has been regarded as Jack London's most racist novel. It was written at the time when America had declared the closure of its frontier and launched overseas expansion. By shaping the image of Joan Lackland， Adventure opens up new gender space for colonial adventure narrative， highlights the domesticity role of the New Woman in stabilizing colonial “home” and constructing national discourse， and represents the essence of capital expansion of “Manifest Domesticity”. With the help of romance narration， Adventure implies the effective colonial ruling model shared by imperialist countries， leading readers to pay attention to the geopolitics of South Pacific. Adventure is of far-reaching significance for studying the hybridity of London's ideas of socialism， racism and nationalism， and exploring the paradoxical relationship between American overseas expansion and its “progressive” ideas.

Key words: Jack London; Adventure; “Manifest Domesticity”
