Final answer:
Luke is the husband of the protagonist, Offred, in Margaret Atwood's novel 'The Handmaid's Tale'. Their relationship is a central part of Offred's memories and emotional journey in the story.
Step-by-step explanation:
Luke is a character in Margaret Atwood's novel The Handmaid's Tale. He is the husband of the protagonist, Offred. In the context of the dystopian society of Gilead, their marriage is invalidated by the new regime because Luke was previously divorced, making Offred an adulteress in the eyes of the state. Offred reflects on her past life and her loving relationship with Luke throughout the narrative. They had a child together before the creation of Gilead and were separated as the regime took power. The absence of Luke and her family greatly impacts Offred's experiences, as she holds onto the memories of her previous life for hope and comfort.
