Dear Debbie

A darkly humorous psychological thriller by Freida McFadden that blends domestic suspense, revenge, and razor-sharp social satire.

The story follows Debbie Mullen, a longtime advice columnist whose popular "Dear Debbie" column has spent years helping women navigate troubled marriages and difficult family lives. But behind her wise advice, Debbie's own life is falling apart. She has lost her job, her teenage daughters are becoming increasingly distant, and her husband appears to be hiding dangerous secrets—at least according to the tracking app she secretly installed on his phone.

After years of being patient, practical, and forgiving, Debbie reaches her breaking point. Instead of continuing to give advice to others, she decides it's finally time to follow her own—and seek payback against the people who have betrayed, ignored, or hurt her. What follows is a twist-filled journey of revenge, deception, and moral ambiguity, where justice and vigilantism become increasingly difficult to separate.

Unlike many of McFadden's earlier novels, Dear Debbie leans more heavily into dark comedy and social commentary while retaining her trademark short chapters, relentless pacing, and shocking twists. Critics have praised its bold antiheroine and satisfying blend of suspense and humor.
