What Is Dear Debbie About? (A Comprehensive Plot Breakdown)

At the absolute center of this whirlwind of a novel is Debbie Mullen. For years, Debbie has cultivated a warm, wise, and deeply trusted public persona as the writer of a massively popular advice column called “Dear Debbie”.Across New England, wives and partners who feel invisible, unappreciated, or outright mistreated by their husbands write in desperate search of sympathy, guidance, and a steady hand to help them navigate their marital crises. Debbie has heard it all. She has read every tale of woe, mediated digital heartbreaks, and consistently guided her readers toward grace, patience, and the “right” decision.

Except there is a deliciously bitter, pitch-black irony at the core of the entire premise: the woman whose entire professional and personal identity is built around giving other people sound, measured life advice can no longer follow her own.

As the novel opens, Debbie’s meticulously constructed life is completely unraveling. It doesn’t just crack; it shatters into a million jagged pieces. First, she loses her job—the very anchor of her routine and authority.Then, things start happening with her teenage daughters that she can’t quite pin down, an undercurrent of adolescent secrecy and hostility that leaves her feeling completely out of her depth.But the ultimate, soul-crushing blow comes when she discovers something horrifying through a tracking app she secretly installed on her husband’s phone. He isn’t just keeping minor secrets; he is living a double life of deception.

For years, Debbie has been the rational one. She has swallowed her anger, taken the high road, and offered endless emotional labor to people who didn’t appreciate it. But this final betrayal is the straw that breaks the camel’s back. It pushes her entirely over the edge.

In a moment of crystal-clear realization, Debbie decides she is officially done being the bigger person. She is done turning the other cheek. She is done offering grace to a man—and a world—that takes advantage of her kindness. She resolves to finally take her own advice. And the terrifying thing is? This time, her advice isn’t about forgiveness or couples therapy. It is about cold, calculated payback.

What follows is a fast-moving, wildly entertaining, and twist-laden descent into madness as Debbie formulates a brilliant, devious plan to get even with the people in her life who have wronged her most. Without spoiling the juicy specifics, the novel leans heavily into the classic “wronged woman turned unstoppable force” trope, blending heart-pounding suspense with moments of genuinely wicked dark comedy.

Meet Debbie Mullen: An Anti-Hero for the Ages

What truly elevates Dear Debbie above a standard, run-of-the-mill domestic thriller is its protagonist. So many psychological thrillers feature passive protagonists—characters who stumble from one terrifying situation to the next, waiting around to be rescued or gaslit into oblivion. On the flip side, some books feature villains so irredeemable that you don’t care what happens to them.

Debbie Mullen occupies that sweet spot right in the middle: the wonderfully messy, deeply satisfying space of the sympathetic anti-hero.

Critics have pointed out how masterfully McFadden balances Debbie’s inherent likability with her increasingly ruthless choices. Kirkus Reviews famously dubbed her a “plucky, puckish” non-traditional antihero, describing the book as “gleefully sadistic, gloriously gratifying revenge fiction.” That juxtaposition—rooting for a woman whose actions grow increasingly extreme and morally questionable—is a hallmark of McFadden’s writing style. You know she is crossing lines she can never uncross, yet you cannot help whispering, Go get ’em, Debbie, under your breath as you turn the page.

Furthermore, Debbie’s background as an advice columnist acts as a brilliant narrative device.For decades, her entire professional existence has revolved around telling other women what they should do when they are mistreated.She has preached empowerment, walking away, and standing your ground. Now, she is forced to hold up a mirror and ask herself the ultimate question: Am I capable of following my own counsel?

That internal conflict gives the novel an unexpected layer of psychological depth. It bridges the gap between a fun, campy revenge plot and a genuine exploration of hypocrisy, self-perception, and the heavy toll of practicing what you preach.

Key Themes Explored in Dear Debbie

While the plot moves at a blistering pace and keeps you guessing until the final chapters, Dear Debbie tackles several timely and resonant themes that give the book real staying power:

1. The Exhausting Cost of Being “The Bigger Person”

Society constantly teaches women, in particular, that they must absorb emotional blows with grace, keep the peace, and rise above conflict. Debbie spends decades doing precisely this—absorbing other people’s pain, managing her family’s emotional landscape, and suppressing her own rage. The novel brilliantly examines what happens when that emotional reservoir finally runs dry and the dam bursts.

2. Surveillance, Trust, and Modern Marriage

The subplot involving the secret tracking app taps straight into a very modern, hyper-digital anxiety. How has smartphone technology completely altered the way romantic partners monitor, check up on, and ultimately mistrust one another? McFadden uses this tech-enabled paranoia to ratchet up the tension from the very beginning.

3. Unapologetic Female Rage

There is a massive cultural appetite right now for stories where women who have been wronged are finally allowed to be angry, calculating, strategic, and completely unapologetic. Instead of suffering quietly in the shadows like gothic heroines of the past, Debbie channels her fury into direct action, reclaiming her narrative by any means necessary.

4. Public Persona vs. Private Reality

Debbie’s entire livelihood depends on projecting an image of warmth, wisdom, and absolute control. The harsh contrast between her public advice-giver persona and her messy, chaotic, behind-closed-doors unraveling forces readers to question how well we ever truly know the people who claim to have it all together.

5. High-Stakes Motherhood

Amidst all the plotting and vengeance, Debbie is still a mother. The inclusion of her complex, secretive teenage daughters injects a layer of authentic domestic stress into the narrative. She isn’t just fighting for her own dignity; she is trying to steer her family through troubled waters even as her own ship is actively sinking.

Critical Reception: What the Reviewers Are Saying

Whenever a new Freida McFadden book drops, the literary world pays attention, and Dear Debbie has been no exception. It has generated massive buzz across major review outlets and bestseller lists alike.

• Booklist (Starred Review): Hailed the novel as an “exciting yarn,” praising McFadden’s uncanny ability to keep pages turning at warp speed while expertly misdirecting the audience with clever, well-placed surprises. The review noted that readers who fell in love with Millie from The Housemaid series will find themselves rooting just as hard for Debbie’s chaotic energy.
• Publishers Weekly: Spotlighted Debbie’s “dark but consistent moral code,” arguing that this strange internal compass is what makes her so endlessly entertaining to root for, even as her decisions skew toward the extreme. They also lauded the book’s “darkly funny” tone, noting how difficult it is to balance genuine suspense with laugh-out-loud dark comedy—a tightrope act McFadden pulls off with ease.
• Kirkus Reviews: Delivered high praise, calling Debbie a “nontraditional antihero for the ages” and cementing the book’s reputation as “gleefully sadistic, gloriously gratifying revenge fiction.”
• Shari Lapena (Bestselling Author of The Couple Next Door): Offered a glowing blurb, describing Dear Debbie as “a perfectly plotted, diabolically fun revenge story,” and adding, “Debbie is such an endearing psychopath—I couldn’t stop reading!” That exact phrase—”endearing psychopath”—captures the exact reason why this book is flying off shelves.

Why Dear Debbie Deserves a Spot on Your Bookshelf

If you are still on the fence about whether to grab a copy, here is a quick summary of why this particular release has captured the reading public’s imagination:

• A Masterclass in Dark Humor: This isn’t a grim, depressing psychological thriller. The injection of sharp, wicked humor keeps the atmosphere buoyant and insanely fun.
• Top-Tier Pedigree:McFadden is a proven global phenomenon whose books have dominated international charts, won major industry awards, and been translated into over forty languages. When you pick up her work, you know you are getting a seasoned storyteller at the absolute peak of her powers.
• Cultural Relevance: The themes of digital surveillance, marital disillusionment, and the reclamation of female agency make the book feel intensely modern and culturally dialed-in.
