The Odd Woman represents a pivotal moment in Godwin’s literary journey, marking a significant evolution from her earlier works, The Perfectionists (1970) and Glass People (1972). This third novel is not only nearly twice the length of its predecessors but also substantially more complex, solidifying its status as a cornerstone in Godwin's development as a novelist.

In The Odd Woman, Godwin expands on the theme of self-definition for modern women, a motif she began exploring in her first two novels. She enriches this exploration by embedding it within a broader historical and literary framework. The novel draws inspiration from George Gissing’s 1893 work, serving as a counterpoint to examine the protagonist, Jane Clifford’s, contemporary challenges. This juxtaposition allows Godwin to delve deeper into the profound connection between the intellectual pursuits of women and their external realities, a depth not attempted in her earlier narratives.

Godwin's focus on character over plot in The Odd Woman signifies a shift towards exploring the intimate intersection of art and life. Her narrative delves into how the echoes of the past linger in the fabric of everyday existence. This thematic focus has continued to influence her subsequent works, reinforcing her interest in how historical and personal histories intertwine in the quest for self-identity.
