Finn is an 18-year-old preparing for college in the rural town of Bone Gap. The townspeople mockingly call him "Moonface" and "Sidetrack" because they perceive him as spacey and easily distracted. He secretly lives with an inability to distinguish facial features, a condition that isolates him and makes it impossible for him to provide a physical description of Roza's kidnapper. He carries heavy guilt over the abduction and desperately wants to mend his fractured relationship with his older brother.

Roza is a 20-year-old botanist who immigrated to America from Poland to study at a university. Before her abduction, she lived in the O'Sullivan family barn and developed a deep connection with the brothers. She actively resents the constant harassment her striking beauty brings, preferring to be valued for her intelligence and gardening skills. Currently held hostage by an obsessive captor, she actively plots ways to free herself.

Sean is an emergency medical technician working in Bone Gap. He surrendered his ambitions of attending medical school to raise his younger brother after their mother abandoned the family.

He holds deep romantic feelings for Roza and struggles to cope with the emotional void left by her absence.

Petey is a local teenager who helps her mother maintain the town's bee hives. She projects a tough, abrasive exterior to protect herself from the townspeople, who frequently mock her facial features and circulate malicious rumors about her. Beneath her defensive posture, she enjoys reading romance novels and yearns for genuine connection. She becomes the only person in Bone Gap to believe Finn's account of Roza's kidnapping.

The Scare Crow is an obsessively controlling man who holds Roza captive in an isolated location. He views people as possessions to be collected and prioritizes his own desires over the autonomy of others. He uses intimidation to maintain control over his environment, demanding that Roza return his affections regardless of her own feelings.

Charlie is an eccentric older man living across the street from the O'Sullivan brothers. He raises chickens that lay brightly colored eggs in pinks and greens, allowing the birds to roost freely inside his home. Originally from Poland, he bonded immediately with Roza over their shared language and heritage before she vanished.

Miguel is a teenager in Bone Gap and serves as Finn's most loyal confidant. He frequently helps Finn with physical labor while offering advice about relationships and local gossip. He struggles with his own insecurities regarding his skin color, which makes him hesitate to pursue his romantic interests.

Honorata is a Polish immigrant who shared a college dormitory with Roza. Harboring deep insecurities about her own worth, she masks her low self-esteem by belittling other girls and assuming Roza is inherently vain. She remains trapped in a relationship with a misogynistic student who treats her poorly.

Jonas serves as the town sheriff in Bone Gap. He dismisses Finn's earnest attempts to report sightings of Roza's kidnapper, suggesting the teenager might be under the influence of drugs. He represents the broader town's tendency to judge individuals based on superficial impressions rather than listening to them.

Amber is a conventionally pretty teenager living in Bone Gap. She maintains a close friendship with Petey despite the town's rigid social expectations. Her presence causes anxiety for Miguel, who fears her family's judgment.

Rus is a massive, wolf-like dog kept by the Scare Crow. Initially violent toward Roza during an escape attempt, the animal slowly forms a quiet attachment to the captive woman as she spends more time outdoors.
