What This Theme Explores
Betrayal and loyalty in The Better Sister are not opposites so much as mirror images—each act of “faithfulness” to one person often requires a betrayal of someone else. The novel probes how competing allegiances to family, marriage, career, and self collide, asking who deserves protection when protecting everyone is impossible. It also interrogates perspective: the same choice can look like treachery or devotion depending on who’s watching and what they’ve suffered. Ultimately, the book argues that loyalty gains its power—and its danger—when it’s forged in fear, shame, and survival.
How It Develops
The story opens with Chloe Taylor naming her sin: “I betrayed my sister.” At the Met Gala, she sides with Adam Macintosh rather than Nicky Macintosh, turning a public spectacle into a private pivot point. What looks like a single choice—helping a man manage his wife’s unraveling—becomes the seed of a new family alignment, one that rewards Chloe in the short term and hollows out the sisters’ bond.
After Adam’s murder, the investigation exposes how every character lives at the fault line between allegiance and deception. Chloe’s affair with Jake Summer violates her marriage, even as it offers emotional refuge. Adam’s secret meetings with the Gentry Group and his quiet cooperation with the FBI betray his firm and partner Bill Braddock in the name of a self he once respected. Ethan Macintosh, masked behind anonymous Poppit posts, betrays Chloe’s trust as he reaches toward his birth mother. Each revelation forces Chloe to choose again and again whom to protect, and at what cost.
In court, loyalty becomes performative and perilous. Jake invokes the Fifth to sheath Chloe’s secret, accepting professional damage to preserve her credibility. Ethan’s testimony reframes Adam’s “respectable” fatherhood as coercive control. Faced with the possibility of losing her son, Chloe recalibrates once more—implicating Jake as a potential suspect to seed reasonable doubt. Betrayal here operates as a grim currency: one betrayal buys another person’s safety.
The final turn clarifies the novel’s moral geometry. Nicky confesses to killing Adam, describing it not as vengeance but as a last-ditch protection of Chloe and Ethan from escalating abuse. Chloe then engineers the cover-up, framing Bill for the murder. In one movement, she betrays the law and an arguably innocent man (of this crime) to seal a renewed sisterhood and stabilize her family. The ending doesn’t resolve the paradox; it insists on it.
Key Examples
-
Chloe’s initial betrayal (the Prologue): Choosing Adam over Nicky at the Met Gala reroutes the family’s center of gravity toward Adam and Ethan, implicitly exiling Nicky. The choice looks compassionate—helping a child in crisis—yet it inaugurates a pattern in which loyalty to Ethan consistently requires sidelining Nicky.
Our story—independent of Nicky—would develop later, but you could say that night marked the story’s beginning. It was the moment I chose Ethan over the rest of my family, which meant I was choosing Adam.
-
Adam’s professional betrayal: Disgusted with corporate law, he compiles a hidden file and cooperates with the FBI against Rives & Braddock and the Gentry Group (see Chapter 36-40 Summary). Professionally, it’s treachery; ethically, it’s a return to the prosecutor he once was. His double life entwines integrity with deceit, illustrating how “doing the right thing” can still rupture trust.
-
Jake’s loyalty on the stand: By taking the Fifth, he protects Chloe and the defense’s strategy despite risking his career (see the Chapter 31-35 Summary). His silence becomes a paradoxical testimony—speechless loyalty that speaks volumes about whom he serves and what he’s willing to lose.
-
Nicky’s ultimate loyalty: In the Chapter 41 Summary, Nicky admits she killed Adam to stop his abuse from destroying Chloe and Ethan. Her confession reframes “murder” as a desperate act of guardianship, insisting that sometimes the only way to keep a promise to family is to break every other promise.
-
Chloe’s final betrayal: Planting the weapon at Bill’s house contaminates the justice system to preserve her son and sister. It’s a calculated sin, revealing that in this world the most durable form of loyalty is the willingness to accept permanent moral stain.
Character Connections
Chloe Taylor centers the novel’s ethical conflict. She first betrays Nicky for Adam, then Adam for Jake; these substitutions reveal her hunger for safety and control. Yet her fiercest loyalty is maternal: to protect Ethan, she will lie, misdirect, and, finally, frame Bill. By the end, her allegiance arcs back to Nicky, but the reunion is built on a shared crime, showing how sisterhood here is remade through secrecy rather than absolution.
Nicky Macintosh inhabits the wound of betrayal and the ferocity of loyalty. Losing Adam and Ethan to Chloe brands her as the family outsider. Yet when she perceives Adam’s abuse worsening, her loyalty to Ethan—and to the sister she still loves—overrides law and self-preservation. Nicky’s choice makes loyalty an active, even violent, verb.
Adam Macintosh is the story’s doubleness made flesh. He presents as the respectable father-lawyer while manipulating those closest to him. His whistleblowing suggests a buried moral core, but his personal betrayals—control, lies, and emotional cruelty—reveal how professional integrity can coexist with intimate harm.
Jake Summer embodies steady, personal loyalty. He protects Chloe’s privacy at profound personal cost and accepts being cast as a plausible suspect if it strengthens Ethan’s defense. His loyalty lacks an agenda, highlighting how rare uncalculated devotion is in a world of transactional ties.
Bill Braddock represents loyalty’s most cynical inversion: allegiance to power and profit alone. He exploits clients, partners, and the law when convenient. As the figure Chloe ultimately sacrifices, Bill exposes how easily institutions become repositories for the guilt others refuse to carry.
Symbolic Elements
Burner phones: These disposable devices map the novel’s shadow network—affairs, secret mother-son contact, and covert deals. Each burner enables a private channel where “true” loyalties operate off the record, turning communication itself into a moral kompromat.
The Met Gala: A glittering stage of performative identity, it’s the perfect backdrop for Chloe’s first betrayal. The event’s obsession with image underscores the book’s link to Public Image vs. Private Reality, where public loyalty signals mask private choices with irrevocable consequences.
Adam’s hidden file: The Redweld folder is a tactile emblem of divided allegiance—orderly, concealed, and explosive. It holds both his conscience and his deceit, proving that the same evidence can redeem a man’s ethics while detonating his relationships.
Contemporary Relevance
The novel’s blurred lines between betrayal and loyalty resonate in an era when personal choices are surveilled and judged in real time. Its portrayal of family triage amid Domestic Abuse and Its Legacy captures the impossible calculus survivors face: which truth to tell, which law to break, whom to save first. The professional crosscurrents—whistleblowing, institutional rot, and strategic silence—mirror dilemmas in corporate and political life, where ethics often collide with self-preservation. Burke’s story insists that the oldest questions—whom do I protect, and what will I pay—remain urgently modern.
Essential Quote
“I betrayed my sister.”
Spoken at the outset, this confession compresses the novel’s entire moral architecture into five words. It primes readers to read every later “loyal” act as potentially treacherous and every “betrayal” as possibly protective, framing the book as an inquiry into whether love is measured by purity—or by the prices we’re willing to pay.
