Who They Are

Brilliant, charismatic, and fatally contradictory, Amy Decker is the spark that ignites Stay Awake. Though she is dead by the time the main narrative begins, her life and choices shape every page: the warmth that made her the center of any room, the ambition that propelled her at the hospital, and the secrecy that detonates the book’s central betrayal.

Amy’s memory is an engine—reconstructed through flashbacks, gossip, and fragments—that keeps the mystery moving. She is the novel’s paradox: the loyal best friend who is also a covert betrayer; the principled idealist who lives comfortably on a wealthy boyfriend’s gifts; the victim whose hidden life forces the protagonist to question everything she believes about love, friendship, and herself.

Personality & Traits

Amy’s charm sits atop a layered moral complexity. She reads as dazzlingly capable and emotionally intuitive—until the revelations land, and those same gifts look like tools for manipulation. Her character invites the unsettling question: was her protectiveness genuine, or a cover for guilt?

  • Intelligent and ambitious: Liv first frames her as “a brilliant doctor who graduated at the top of her class” (Chapter 1), a tireless intern with plans to serve abroad.
  • Charismatic and tactile: Frequently described as warm and physically affectionate, Amy effortlessly attracts favors and upgrades—benefits of a charisma she also knows how to wield.
  • Deceptive and duplicitous: She conducts a clandestine affair with Marco while advising Liv to end that very relationship, a hypocrisy sharpened by the intimacy of their friendship.
  • Protective—on the surface: Her blunt counsel about Liv’s love life feels caring until it reads as self-serving, angled toward clearing the path for her own secrets.
  • Idealistic yet pragmatic: Dreams of humanitarian medicine coexist with a polished lifestyle funded by a wealthy surgeon’s gifts, suggesting a talent for moral compartmentalization.

Character Journey

Because Amy is dead in the present timeline, her “development” is the reader’s evolving perception. Early flashbacks present her as the ultimate best friend—magnetic, loyal, and driven. Piece by piece, that ideal dissolves, revealing a covert life that reframes her as both victim and architect of the novel’s emotional wreckage. Her arc traces the collapse of an illusion, repositioning her at the heart of Trust and Betrayal: the person Liv trusted most is the person who cut deepest.

Key Relationships

  • Liv Reese: Amy and Liv share a sister-level intimacy that makes the betrayal catastrophic. Amy’s counsel about Liv’s relationship reads as protective until it’s exposed as self-interested, turning their bond into the psychological fault line that splits open Liv’s memory and sense of reality.

  • Marco Reggio: Their affair is passionate and clandestine, carried out behind the back of a mutual friend. What begins as secrecy curdles into doom; the illicit nature of their relationship foreshadows the violence that ends both their lives and propels the plot.

  • Brett Graham: The affluent, controlling boyfriend who showers Amy with gifts holds more power in the relationship than she does. Amy privately plans to leave him—a decision that intersects with obsession and ends in lethal exposure when her infidelity comes to light.

Defining Moments

Amy’s life is revealed through charged scenes that reframe what we think we know—about her, and about everyone orbiting her.

  • The birthday dinner (Chapter 24)

    • What happens: Amy shines in a room that contains both her official boyfriend and her secret lover, a glittering social high-wire act.
    • Why it matters: Dramatic irony exposes her double life; the scene crystallizes her charisma as the very thing that helps sustain deception.

  • The rooftop conversation (Chapter 39)

    • What happens: Amy urges Liv to break up with Marco, calling him an “asshole,” while she herself is sleeping with him.
    • Why it matters: It’s hypocrisy at its apex—and a psychological tell. The advice reads as both performative care and an attempt to control the narrative before the truth leaks out.

  • The discovery of the bodies (Chapter 42)

    • What happens: Amy and Marco are found murdered in Amy’s bed, a tableau of intimacy and violence.
    • Why it matters: This is the trauma that shatters Liv’s timeline, binding Amy’s secret life to the book’s exploration of Memory and Identity.

Symbolism

Amy symbolizes the seduction and peril of surfaces—the glossy friend whose bright exterior masks a storm of contradictions. As the embodiment of The Unreliability of Perception, she shows how appearances manufacture trust, how charisma can cloak duplicity, and how love can be the most convincing disguise of all. Her character warns that the most dangerous lies are the ones we’re eager to believe.

Essential Quotes

“Amy is a brilliant doctor who graduated at the top of her class. I love her to death, but she can be scatterbrained about updating me on what she considers mundane things...”
— Liv’s initial, fond description (Chapter 1)

This early sketch casts Amy as both exceptional and endearingly imperfect—smart enough to excel, human enough to forget to text back. The warmth here primes readers to trust Amy, making later revelations more destabilizing.

“Dr. God Complex? All he talks about is his patient list and how he’s single-handedly saving humanity. He has zero interest in discussing anything that isn’t about him. As for Amy, every time we meet up, we argue over politics. It totally kills the vibe.”
— Marco’s assessment (Chapter 7)

Marco’s dig at Brett and friction with Amy hint at combustible dynamics long before the affair is exposed. The line plants suspicion and signals that Amy’s relationships are already triangulated and tense.

“You’re wasting your time on Marco. That relationship will never go anywhere. Break up with him. Go meet someone new.”
— Amy’s advice to Liv (Chapter 30)

On first pass, this sounds like tough love; in hindsight, it’s strategic misdirection. The quote captures Amy’s blend of intimacy and manipulation—counsel that protects her image while obscuring her betrayal.

I distinctly hear her say: “This has gotten out of hand.”
— Liv overhears Amy’s phone call (Chapter 35)

This overheard fragment is the pivot where concern curdles into dread. It reveals Amy’s awareness of mounting risks and suggests she’s losing control of a secret she can no longer manage.

“Amy and Marco are in her bed. Naked, with the sheet down to their waists... Their eyes are unblinking and there are holes in their chests.”
— The murder scene description (Chapter 42)

The stark, clinical detail fuses intimacy and violence, collapsing Amy’s private life into a single horrifying image. It transforms her from a memory to a crime scene and fixes the trauma that powers the novel’s investigation.
