The central theme of The Golden Couple is the deceptive nature of appearances, which is spoken to by the book’s title itself. The “golden couple” in question may appear perfect at first glance, but they are in fact in a deeply fractured relationship. Avery recognizes this in their very first meeting when she accuses Marissa of orchestrating picture-perfect moments in her marriage. When Marissa relays a fond memory, Avery retorts: “That’s an Instagram post. Give me something real” (14). The narrative then summarizes the supposed “golden couple”: “Avery has cut to the core of what their marriage has become: curated moments served up in public, while in private the emptiness between them slowly expands” (15). The book’s conflict is immediately established: Don’t believe what you see on the exterior.

This applies not only to couples but also to individuals. Matthew’s character is the ultimate proof of the book’s exploration of the idea that you can’t trust outward appearances. Matthew appears to be a loving husband who wants to make things work with his wife, even after her infidelity. He has photos of her in his office, which reflects the image-forward, “Instagram” nature of appearances in the novel.
