In Ian McEwan's novel "Sweet Tooth," the absence of female characters is likened to a barren landscape, devoid of vitality and interest. This metaphor emphasizes the vital role women play in storytelling, as they bring depth, perspective, and emotional richness to narratives. Without their presence, stories become monotonous and uninspiring, much like an uninhabited desert.

This quote reflects a broader commentary on literature and gender representation. McEwan suggests that novels lacking female characters fail to capture the complexity of human experience. By integrating diverse voices, including those of women, writers create a more engaging and representative literary world that resonates with a wide range of readers.
