In the way that Marxism has readers question why they are treated they way they are, Queer theory challenges readers to read more into the binary of gender in literature as well as sexuality. Sexuality is mostly portrayed heternormative in writing however some critics use queer theory and make is as ambiguous as possible so readers have to rethink how they feel about the gender expressiona nd sexuality expression in the writings. This kind of critique also, is similar to feminism in how it questions masculinity and femininity as well as power dynamics between characters and how this affects the writing. 

Rossetti also uses queer theory in “Goblin Market” with the ambiguity between the “sisters” and their sexuality drawing a very large grey area as to why they are so sexual yet call each other sisters. This thing of calling them sisters can make the queerness fall below the radar of those who are opposed to it yet would stick out to those who are not opposed or able to pick up on the queer notes in the writing but still questioning the relationship between the two.
