Return to Grace
Codi Noline, a biology teacher haunted by past failures and a recent miscarriage, flees her life in Washington and returns to Grace, Arizona, the small, isolated town where she grew up. Her father, Homer Noline, a retired doctor, is showing signs of dementia and needs care. Codi feels a deep disconnect from her past and her father, who has always been emotionally distant. She takes a job teaching biology at the local high school, where she immediately notices the town's struggle with a mysterious illness affecting the local sheep and, potentially, the people. Her return is marked by a deep sense of displacement and a search for meaning.
The Looming Crisis
As Codi settles into Grace, she observes unsettling patterns. The local sheep are dying from a strange illness, and the town's fruit trees are failing. Her students also exhibit unusual health problems. Codi, with her scientific background, suspects an environmental cause. She learns about a historic abandoned copper mine upstream, the Black Mountain Mine, and the persistent rumors of contamination. She attempts to discuss her concerns with the townspeople, but many are dismissive, resigned, or too fearful to confront the powerful mining company that once dominated the region.
Loyd Peregrina and the Apache Way
Codi reconnects with Loyd Peregrina, an Apache man she knew in high school. Loyd is a trainman and a man deeply connected to the land and his cultural heritage. He offers Codi a stark contrast to her own scientific, often bleak, worldview. Their relationship slowly rekindles, and Loyd introduces Codi to Apache traditions, dream interpretation, and a philosophy that emphasizes interconnectedness with nature and community. His calm wisdom and grounded presence begin to chip away at Codi's cynicism, though she initially resists his spiritual approach to life's problems.
Emory and the Stitch and Bitch
Codi's younger sister, Emelina 'Emory' Noline, returns to Grace after years away. Emory is outgoing and dedicated to social justice, a stark contrast to Codi's introverted nature. Emory quickly becomes involved with the 'Stitch and Bitch' club, a group of local women who gather to quilt and discuss town affairs. Through this group, Codi learns more about the town's history, its struggles, and the quiet resilience of its inhabitants. The women, particularly the elder Inez, provide Codi with a sense of belonging she hasn't felt in years.
Unraveling the Past
As Codi cares for her father, Homer, she sifts through his belongings and discovers old photographs and letters that reveal a hidden past. She learns that her mother was a member of the local Apache tribe, and that Homer, a white doctor, was deeply involved in the community's health struggles, particularly concerning the mine. These revelations shatter Codi's understanding of her family and herself, forcing her to confront the racial and cultural divides she had previously ignored. The truth about her heritage explains much of her father's emotional distance and her own feelings of not belonging.
The Mine's Legacy
Driven by the mounting evidence of illness and her own scientific curiosity, Codi, with Emory's support, investigates the Black Mountain Mine more thoroughly. They gather water samples, research historical records, and interview older residents. Their investigation confirms that the mine's tailings have been leaching heavy metals, specifically lead and arsenic, into the town's water supply for decades. This environmental contamination is the cause of the widespread health problems, including the sheep's illness and her father's dementia, which Codi realizes is lead poisoning.
Community Action and Resistance
Armed with proof of contamination, Codi and Emory, alongside the women of the 'Stitch and Bitch' club, decide to take action. They organize a town meeting, present their findings, and galvanize the community to demand accountability from the defunct mining company, which is now owned by a larger corporation. The women, led by Inez and Emory, demonstrate courage and solidarity, facing intimidation and skepticism from some townspeople. They plan a protest and a legal challenge, asserting their right to a healthy environment.
Homer's Confession
As Homer's health deteriorates, he has moments of lucidity where he reveals more about Codi's mother, Alice, and the tragic circumstances of her death. He confesses that Alice died in childbirth after being exposed to the mine's toxins, and that he, as a doctor, had tried to warn the company but was silenced and marginalized. He also reveals that Codi was not his biological child, but Alice's daughter from a previous relationship, and he adopted her. This final revelation about her parentage impacts Codi, solidifying her connection to Grace and its people, as well as her understanding of her father's quiet suffering and protection.
The Water Diversion
With legal avenues proving slow and difficult, and the community's health rapidly declining, the women of Grace, including Codi and Emory, take matters into their own hands. They decide to divert the contaminated river away from the town's water source, a bold and potentially illegal act of civil disobedience. This act symbolizes their collective defiance and their commitment to protecting their future. Loyd Peregrina, while not directly participating in the diversion, provides spiritual and logistical support, reinforcing the idea of community self-reliance.
A New Beginning for Codi
Following the water diversion and Homer's passing, Codi experiences a transformation. She accepts her heritage, her role in Grace, and her love for Loyd. She decides to stay in Grace, committing herself to the community's future and to continuing her work as a teacher and advocate. Her relationship with Loyd deepens, founded on mutual respect and a shared vision for a sustainable life. Codi, once rootless and adrift, finds her place, purpose, and a renewed sense of hope, embodying the novel's themes of belonging and environmental justice.
