Worried about this procedure that is going to make her "better," Calliope goes to the library to do some research.
Under "hermaphrodite," Webster's dictionary refers to "See synonyms at Monster" (4.2.43). It's a really rough moment in the book.
As if Calliope wasn't under crisis enough, she finds out that the doctor is going to perform a small procedure to keep her a girl. "You won't be Raquel Welch, but you won't be Twiggy either" (4.2.65), he says.
When Dr. Luce leaves the room, Calliope reads her report and discovers that Dr. Luce has been lying. Genetically speaking, Calliope is primarily male.
Wanting to stay male, Calliope decides to runs away. She leaves a note for her mom and dad in the hotel room and notes, "It was the last time I was ever their daughter" (4.2.109).
