What is the main setting in the novel, All Grown Up?

New York City, the city where Andrea was born and raised, is where she returns after a failed stint in graduate school in Chicago. Her earliest memories of the city include her father's death and a near-rape as a teenager. As an adult, the city feels oppressive to her, as she is isolated and unable to connect with the people around her. The nature of the city as a fast-paced environment allows her to not fully confront her problems and keep people at a distance.
