Foe by J.M. Coetzee is narrated by Susan Barton, the only female character who is cast away on the same island as Robinson Crusoe and Friday. Susan struggles for independence and power in a society that views her as irrational and less valuable due to her gender. Throughout the novel, Susan describes the island as "Cruso's island" and sees herself as a subordinate to the male characters. Susan is an unreliable narrator, and the novel examines her shifting perspectives and desire for freedom within the constraints of her society.
