Dear Debbie

</syntaxhighlight>

Dear Debbie is a psychological thriller novel written by Freida McFadden, published by Poisoned Pen Press on January 27, 2026. The novel represents a standalone work from the #1 New York Times bestselling author, exploring themes of vengeance, morality, and domestic deception through the lens of a troubled advice columnist who decides to take matters into her own hands.

Plot

The novel centers on Debbie Mullen, a renowned advice columnist whose column, also titled "Dear Debbie," has long served the women of New England. Through her work, Debbie has heard countless stories from wives dealing with neglect, belittlement, and abuse, and she has always offered thoughtful, practical guidance to those seeking her counsel.

However, Debbie's own life begins to unravel rapidly. She loses her job at the newspaper after one of her advice columns—in which she counseled a reader to pursue divorce—is deemed controversial by her editor-in-chief. Simultaneously, her carefully constructed domestic life reveals itself to be built on deception. Her daughters, Lexi and Isabel, are hiding secrets of their own, and her husband Cooper appears to be unfaithful, according to monitoring software Debbie has installed on his phone. Her husband's boss denies him a long-deserved promotion, and her youngest daughter is cut from the soccer team by a coach who criticizes her appearance.

As her frustrations mount, Debbie abandons her philosophy of being the "bigger person." Instead, she decides it is time to apply her own advice to those around her—but with a far darker twist. What follows is a calculated campaign of revenge against those who have wronged her or her loved ones, leading to shocking consequences. The narrative unfolds through multiple first-person perspectives, including Debbie, her husband Cooper, and Harley, a central figure in the unfolding drama. Interspersed throughout are increasingly unhinged drafts from Debbie's advice column, revealing the darkening nature of her thoughts.

Themes

The novel explores several interconnected themes relevant to contemporary domestic fiction:

Morality and Justice

At its core, Dear Debbie examines questions of personal justice and moral code. Debbie operates according to her own consistent, if twisted, moral framework—she targets those who deserve punishment in her view, making her a complex antihero rather than a conventional villain.

Domestic Deception

The novel investigates the hidden lives within marriages and families, exploring how spouses and children conceal truths from one another and the consequences of these deceptions coming to light.

Revenge and Female Agency

The work functions as dark revenge fiction that examines what happens when women, pushed beyond their limits, choose to take justice into their own hands rather than accepting mistreatment or injustice passively.

Appearances versus Reality

A recurring theme involves the gap between how people present themselves publicly and who they actually are in private. Debbie maintains an image of a calm, reasonable wife and mother while harboring increasingly sinister intentions.

Character Analysis

Debbie Mullen is presented as a complex antihero—a woman whose empathy for others and desire to help have made her an excellent advice columnist, yet whose experiences have made her capable of cruelty and manipulation. Her characterization subverts traditional notions of the nurturing mother and wise counselor. Rather than being passive in the face of mistreatment, she becomes an active agent of her own narrative, though readers must constantly question the morality of her actions.

Reception

Dear Debbie has received predominantly positive reviews from both critics and readers. The novel debuted on multiple bestseller lists, including the #1 New York Times bestseller list, and has been praised for its engaging narrative and complex protagonist.

Critical reception includes:

Kirkus Reviews called it "gleefully sadistic, gloriously gratifying revenge fiction," praising Debbie as "a nontraditional antihero for the ages."

Booklist gave the novel a starred review, describing it as an "exciting yarn" and noting that McFadden is "an expert at keeping the pages turning and misdirecting her audience."

Publishers Weekly noted that "Debbie's dark but consistent moral code makes her easy to root for...this darkly funny thriller will put a wicked smile on readers' faces."

Shari Lapena, author of The Couple Next Door, called Debbie "such an endearing psychopath―I couldn't stop reading!"

Readers have particularly praised the novel's pacing, dark humor, and the surprise twist that concludes the narrative. Many reviewers noted that the character of Debbie is a departure from traditional female protagonists, being genuinely intelligent and self-aware about her own psychopathic tendencies.

Some readers noted that the early portions of the novel move more slowly than later sections, and content warnings have been noted for sensitive subject matter including a rape scene.

Critical Context

Dear Debbie has been compared favorably to works by authors such as Gillian Flynn and Alice Feeney, who are known for writing psychologically complex female characters in dark, twisty narratives. The novel represents a shift in tone for McFadden from some of her other recent work, with critics noting that it combines entertainment value with emotional depth and genuine characterization.

The inclusion of advice column excerpts throughout the narrative serves a dual purpose—they provide dark humor while also revealing Debbie's psychological deterioration as the drafts become increasingly unhinged and violent in their recommendations.
