Marie Powell finds herself trapped in a stifling marriage to the rigid and demanding poet John Milton, forcing her to navigate the constraints of 17th-century domestic life. Marie, a young woman of spirit and intellect, enters into a union with the austere Puritan writer, only to discover that her husband expects total submission and intellectual silence. The narrative follows her attempts to maintain her identity against his domineering personality and his refusal to acknowledge her own creative potential. Set against the backdrop of the English Civil War, the story utilizes a first-person perspective to detail the logical and physical limitations placed upon women of the era. The conflict centers on the friction between Marie's desire for autonomy and the suffocating expectations of her husband's household.

Readers frequently highlight the meticulous historical detail that Graves employs to reconstruct the atmosphere of the 17th century. Discussion often centers on the author's ability to humanize a figure who is typically viewed only through the lens of her husband's literary fame. Critics observe that the pacing remains steady, prioritizing the internal development of Marie over external action sequences. The narrative is often noted for its sharp, unsentimental prose that avoids romanticizing the period. Many readers appreciate the balanced portrayal of the domestic friction, which avoids turning the conflict into a simple caricature of good versus evil.
