This chapter considers Christina Stead as a transnational writer, who travelled across continents and through political contexts. It argues that her work is bound together by a “marine aesthetics” and surveys how this plays out in the key phases of writing life: an early period in London and Paris, a middle period in America, and late period, in Europe, England, and Australia. Stead is a political writer of the twentieth century, but also a formal realist whose works continue to challenge the novel genre today.
