Artemisia is a wild mustang who functions as a deuteragonist and as a multifaceted symbol in Maya’s journey. She is a Paint horse, a breed of Western stock horses with dark and white coloring. Her character arc runs parallel to Maya’s, exploring themes of family, loss, and survival in the natural world. As a lead mare, she is a confident and capable leader who bears the responsibility for the safety of her band. Her name is a reference to the painter Artemisia Gentileschi, and this connection is designed to suggest that the horse herself is a natural work of art. Her journey mirrors Maya’s own struggles, for just as Maya is orphaned and removed from her repressive home, Artemisia loses her family during the government gather and is left isolated and vulnerable. This shared experience of sudden loneliness and the need to survive becomes the foundation for the connection between Artemisia and Maya, which is one of mutual healing. Artemisia loses her foal, Klee, to a predator, and the same time, Maya is still grappling with the loss of her parents and the emotional void left by her grandmother. When they find each other in the wilderness, they are two solitary survivors who form a new, unspoken family.

Artemisia, who was once Maya’s mother’s horse, becomes a living link to Maya’s past and a catalyst for her future. Ultimately, Artemisia symbolizes untamed freedom. Her life in the wild represents an existence completely opposite to Maya’s initial confinement, and Maya’s final, painful choice to release Artemisia concludes the novel’s focus on Reconciling Human Connection With the Natural World, for Maya understands that true stewardship is based on respect, not the need to control another being.

Aunt Vi serves as Maya’s primary mentor and embodies the values of the Wyoming wilderness: independence, truth, and a deep connection to the natural world. As such, she is the antithesis of Grandmother Menetti, providing Maya with a rustic, open environment that transcends the sterile cruelty of Grandmother’s home in Pasadena. As a former art history professor who spends her summers guiding trips and studying wild horses, Vi models a relationship with nature that is based on respect and observation, and her practice of naming horses after famous artists reinforces the idea that nature is a masterpiece to be honored.

Vi’s mentorship is crucial to Maya’s development, though she is often tough and demanding and has no tolerance for Maya’s lies and manipulations. During a difficult riding lesson, Vi refuses to let Maya give up after falling off a horse. When Maya cites her parents’ deaths as a reason to quit, Vi yells, “Are you going to use their deaths as an excuse for everything that you can’t do or are afraid to try, for the rest of your life?” (164). Vi’s confrontational style helps Maya to break free from her ingrained habits of evasion and self-pity, and even as Vi provides the girl with the practical skills of horsemanship and survival, she also offers her the truth about her family’s past. By sharing stories about Maya’s mother, Vi helps Maya to construct an authentic identity that honors her mother’s legacy of strength and fearlessness, replacing the falsehoods created by Maya’s paternal grandmother.

As the novel’s initial antagonist, Grandmother Agnes Menetti represents the forces of repression, control, and psychological confinement that Maya must overcome. Her entire existence is a monument to her unresolved grief over the death of her son, Gregory (Maya’s father). This grief has curdled into a bitter and controlling nature, which she uses to crush Maya’s spirit. Her home environment is sterile, colorless, and suffocating, with plastic-covered furniture and an obsessive focus on white paint and order. In Maya’s view, the house is a prison built to keep out the messiness of life, emotion, and memory.

Grandmother Menetti treats Maya with unalloyed antagonism, but her cruelty arises from her own unaddressed sorrow. Specifically, she blames Maya’s mother for her son’s death, referring to her as “that woman” and claiming that Ellie’s “obsession with horses” (30) led to the accident that killed them both. As a result, she makes a systematic effort to erase her daughter-in-law from the family history, even going so far as to cut her image out of photographs and forbid Maya to mention Ellie’s name. She therefore perpetuates The Inherited Burdens of Grief and Memory, passing her trauma to Maya in the form of silence and lies. While her actions are harmful, they stem from a place of loss, and she is ultimately a tragic figure who remains trapped in her own past. Her sudden stroke acts as the inciting incident that frees Maya to begin her journey toward healing and self-discovery in the wilds of Wyoming.

Payton, Maya’s cousin, initially torments Maya but eventually becomes a genuine friend and ally. When Maya first arrives, Payton is territorial and antagonistic, viewing her as an unwelcome intruder in his summer sanctuary. He therefore engages in pranks such as setting off firecrackers and putting a mouse in her tepee, acting out a childish expression of his resentment. This initial conflict compels Maya to navigate a new, challenging social dynamic. However, the turning point in their relationship occurs after Maya is thrown from her horse, for Payton’s immediate concern reveals his capacity for empathy. As Aunt Vi forces them to work together, their shared experiences forge a reluctant alliance that slowly blossoms into friendship. Payton also makes amends for his misbehavior by finding and returning Maya’s favorite toy horse, which he had thrown away. By the end of the novel, he has become a key part of the supportive family that helps Maya to heal, and it is clear that he, too, is capable of growth and change.

Moose, Maya’s maternal grandfather, shows the lost girl an easy emotional openness, providing her with an immediate, loving anchor in the unfamiliar world of Wyoming. Contrasting with Grandmother Menetti’s abusive expressions of grief, Moose is openly emotional, and he is frequently moved to tears by memories of sadness and joy alike. Aunt Vi explains that he “wears his heart on his sleeve” (176), and this image shows Maya a healthy, honest way of processing loss and grief. When he calls Maya “Maya-bird” (129)—a variation of the nickname he had for her mother, “Ellie-bird” (72)—this quirk instantly forges a link to the maternal past that Maya has long been denied, and Moose becomes a crucial figure in her healing process.
