Sasha Cadell: The Reluctant Medic of Beneath

Overview

Sasha Cadell is the twenty‑three‑year‑old protagonist of Ariel Sullivan’s debut novel Beneath. A skilled medic who earned the ominous nickname “Death’s Angel” for sitting with dying patients when others fled, Sasha survives a nuclear war that killed most of her family and forced her into the underground shelter of Haven. At the story’s opening, she works in the Expansion Sector, deliberately isolating herself from others. Her hatred of humanity—born from trauma—collides with an inescapable duty when Commander Tristian Hayes petitions for her transfer to the elite Force unit. Sasha is thrust into a surface mission that may be Haven’s last hope, forcing her to confront her past, her self‑loathing, and the possibility of belonging.

Plot Role

Sasha serves as the central point‑of‑view character. Her arc moves from a solitary, hostile survivor to a reluctant but committed member of Unit Seven. The plot hinges on her medical expertise, her gradual acceptance of trust, and her eventual decision to “try” despite overwhelming grief. Key turning points include:

• Forced transfer to the Force (Chapter 3)
• Choosing Levi as her partner (Chapter 11)
• Saving Levi’s life on the surface (Chapters 18–20)
• Swapping health‑score charts to protect Levi (Chapter 22)
• Uncovering the conspiracy around Haven’s dying supplies (Chapter 13 onward)
• Confronting Commander Burdon and discovering the spy “Snake” (Chapter 37)

Motivations and Traits Shown Through Actions

Sasha’s primary motivation is self‑preservation wrapped in guilt. She believes she is beyond redemption, having failed to protect her siblings—Eli, Lara, and later Lily. This belief manifests as a protective wall of cynicism and cruelty. She deliberately pushes people away, as seen when she threatens to sleep with Jaxon to hurt Tristian (Chapter 4). Yet her actions betray a deeply buried morality:

• She falsifies Ward charts to protect patients from the health‑score system (Chapter 5, 22).
• She treats Bretta in a secret closet, hiding the illness from authorities (Chapter 26).
• She donates her own blood to save Levi (Chapter 18).
• She carries the unit’s vow—“We go out as one, we come back as one”—while performing field medicine (Chapter 18).

Her defining trait is resilience born of loss. The “beast” inside her—a metaphor for her trauma—rages when she freezes in the House simulation, triggered by a hologram of a boy resembling her brother Eli (Chapter 8). But she repeatedly drags herself back from the brink, climbing the rope in defiance of her ghosts (Chapter 11) and finding a moment of peace asleep beside Levi in the Ward (Chapter 22).

Chronological Arc

Sasha’s journey follows a classic reluctant‑hero trajectory:

1. Refusal: She turns down Tristian’s initial offer to join the Force (Chapter 1). She fights off an assault in the tunnels, foreshadowing her survival instinct.
2. Induction: Transferred against her will, she feigns incompetence, refusing to fight during sparring (Chapter 5) and failing the rope climb.
3. Slow Integration: After the bounty on her head (Chapter 10), Unit Seven protects her. She accepts Levi as her partner and begins to “try” (Chapter 11).
4. Crisis: In the Abyss, she saves Levi from a fatal trap, using her father’s medical lessons and performing a field transfusion (Chapters 18–20). The experience cracks her shell.
5. Act of Rebellion: She alters Levi’s health chart, risking punishment (Chapter 22). Dr. Kumar reveals the true meaning of “Death’s Angel”—she protects life.
6. Deepening Bonds: She shares a vulnerable kiss with Tristian (Chapter 24), then avoids him out of shame (Chapter 25). She loses Dr. Kumar to the illness (Chapter 31).
7. Confrontation: She helps uncover the conspiracy, switches ID bands with Levi, and faces Burdon’s accusation (Chapter 37). She identifies Henderson as the spy.
8. Epilogue: As Phoenix, she works in Expansion, declaring she now lives for others. The story ends open, with Kaleo hinting at darker choices ahead.

Relationships

• Tristian Hayes: Tristian is the first person to see past Sasha’s armor. He petitions for her transfer, defends her against Burdon, shares intimate vulnerability (Chapter 24, 31), and confesses love (Chapter 36). Sasha’s fear of being “too broken” repeatedly pulls her away.
• Levi (Raven): Levi becomes Sasha’s partner and anchor. He challenges her to try, forgives her for his injury, and insists she is worthy of good things (Chapter 25). Their bond is built on mutual trust and silent understanding.
• Unit Seven: Ingrid initially views Sasha as a replacement for her dead partner Lily. Damien, Isla, Patrick, and Rumi gradually accept her. The unit’s rotating protection (Chapter 9) and shared coffee rituals (Chapter 14) symbolize her new family.
• Dr. Kumar: The mentor who named her “Death’s Angel.” He protects her tracks, reveals the truth about her nickname, and extracts a promise from her sister Lara. His death devastates Sasha (Chapter 31).
• Lily: The deceased cadet whose ghost haunts Ingrid and Sasha. Sasha’s memory of Lily’s death (Chapter 28) fuels her guilt.
• Jaxon: A former sexual partner; Sasha uses him to hurt Tristian but later humiliates him (Chapter 6). He is assigned as Levi’s replacement (Chapter 20), a forced partnership.

Key Decisions and Consequences

Theme and Symbol Connections

Conformity vs. Rebellion – The opening chapter’s single word “Conform” frames the ethical struggle. Sasha rebels against the health‑score system, the forced transfer, and the requirement to break her unit. Her rebellion is quiet—a forged chart, a hidden patient—but each act affirms her humanity.

Trauma and Healing – Sasha’s flashbacks to Eli’s death, her mother’s rejection, and Lily’s final words are woven into every chapter. Her healing is incremental: climbing the rope, sleeping peacefully beside Levi, allowing Tristian’s kiss. She learns to “try” without erasing the past.

Trust and Betrayal – The betrayal of Lily’s death, Burdon’s bounty, and the revelation of the spy Henderson echo the epigraph about controlling the past. Sasha’s arc is about relearning trust in a system designed to punish it.

Survival vs. Living – Sasha’s early existence is pure survival—sleeping alone, rejecting connection. By the epilogue, she lives for others, a shift from enduring to meaning.

Power and Control – Commander Burdon, the health‑score system, and the hidden conspiracy all represent control mechanisms. Sasha’s final decision to tamper with the system and later switch band IDs is a direct challenge to that power.

Symbols

• Death’s Angel – The name that shifts from omen to promise of protection.
• The knife – Her father’s military knife, lost in the first chapter and later returned (Chapter 13), links her to her family’s legacy.
• The rope climb – A literal and metaphorical ascent out of despair.
• The secret closet – A hidden space of compassion against the system.
