What is an example of symbolism in the novel, All the Ugly and Wonderful Things?

Constellations symbolize being grounded in the novel. Wavy's life is highly unstable. She has a drug addict mother and is bounced around from Brenda's home, to her grandma's, to a halfway house to the farmhouse in Powell. While her life may be unpredictable, the stars are constant. Every night they can be seen shining in predictable patterns. Wavy finds comfort in this because they make her feel grounded and centered. As she opens up to Kellen, she includes him in this feeling. Kellen quickly becomes an avid learner and uses constellations to to be part of Wavy's life.
