Read the excerpt from Homecoming. At half-past eight, Dicey herded everybody back into the mall, to use the bathrooms they had found earlier. Later, Sammy and Maybeth fell asleep easily, curled up along the back seat. James moved up to the front with Dicey. Dicey couldn't see how they were both to sleep in the front seat, but she supposed they would manage it. James sat stiffly, gripping the wheel. James had a narrow head and sharp features, a nose that pointed out, pencil-thin eyebrows, a narrow chin. Dicey studied him in the darkening car. They were parked so far from the nearest lamppost that they were in deep shadows.

With her brothers and sisters near, with the two youngest asleep in the back seat, sitting as they were in a cocoon of darkness, she should feel safe. But she didn't. Though it was standing still, the car seemed to be flying down a highway, going too fast. Even the dark inside of it was not deep enough to hide them. Faces might appear in the windows at any time, asking angry questions.

Based on the excerpt, which best describes Dicey’s mood?
