The novel contains a variety of symbols for identity, changes or discoveries about identity, or hidden identities. For example, Serafina’s eyes and interesting hair-color symbolize her individuality. These features also represent her connection, literally and figuratively, to her mother, who shares similar features. When she dons the dress Braeden gives her, it marks her maturation and symbolizes her chosen transformation into someone who faces new situations with courage and confidence. Her struggle—and success—with walking slowly down the hall in the dress to bait Mr. Thorne (instead of catching him while hiding herself) represents a redefined identity. Trying on the cloak symbolizes her continued search for answers about who she is deep inside and what her contributions to the world should be. Finally, while she has spent all of her life hidden in isolation, Serafina at last stands in the open at the side of the forest at the end of the story, and this moment symbolizes how she will grow and change to welcome—and be welcomed by—others in her life.

The forest is dark and foreboding beneath its dense canopy. Throughout most of the story, it symbolizes danger and the unknown. Its trees trap Braeden’s and Serafina’s carriage, making them vulnerable to attack from the Man in the Black Cloak.
