Rule: When you write about a novel or play, the only references to its being a novel or play should come in your citations. In the body of your writing, write about what happens in the story (the context) rather than about the book or play (the form). The only exception to this rule is if the prompt asks you to explain the importance of the form or something specific about the form (a piece of flash fiction, chapter titles in a book, a sonnet, etc.) in making meaning.
Examples:
Wrong: In Act I, Macbeth says, "If it were done when 'tis done, then 'twere well it were done quickly."
Okay: Macbeth doesn't like waiting around to kill King Duncan. He says, "If it were done when 'tis done, then 'twere well it were done quickly" (I.vii.1-2).
BEST: Macbeth doesn't like waiting around to kill King Duncan and admits that if the murder “were done when 'tis done, then 'twere well it were done quickly" (I.vii.1-2).
Wrong: On page 161, Huck Finn says, "It was a close place."
Okay: When Huck struggles with his decision about Jim, he says, "It was a close place" (161).
BEST: Huck acknowledges that his decision about Jim is “a close place” (161).
Wrong: In the novel, Nick tries to reserve judgment.
Better: Nick tries to take the advice of his father to reserve judgment.
Wrong: Early in the book, Buttercup becomes the most beautiful woman in the world.
Better: After she learns of Westley's death, Buttercup becomes the most beautiful woman in the world.
Wrong: In Act III, Orlando carves Rosalind's name on every tree he can find.
Better: To express his new love for her, Orlando carves his name on every tree he can find. (III.ii.5-10)
Wrong: In chapter four, Holden talks about Stradlater and Jean Gallagher.
Better: After Holden leaves Ackley, he talks about Stradlater and Jean Gallagher.
