About Buchanan-Renard-MacKenna
Julie Garwood’s Buchanan-Renard-MacKenna series is a loosely connected collection of contemporary romantic-suspense novels built around large families, enduring friendships, federal investigations, and relationships formed under dangerous circumstances. The books marked Garwood’s successful transition from historical romance into modern crime and suspense, replacing medieval castles and Highland clan conflicts with serial killers, organized crime, political corruption, stalking, and covert investigations. Her essential style remained unchanged: capable heroines, protective but emotionally guarded heroes, affectionate family interference, sharp dialogue, and humor that prevents even the darkest plots from becoming relentlessly grim.
The sequence begins with Heartbreaker, in which FBI agent Nick Buchanan becomes involved in the hunt for a calculating killer who has targeted Laurant Madden, the sister of Nick’s closest friend. Nick’s large Boston family provides the foundation for much of the continuing series. His siblings and relatives move between supporting and leading roles, allowing readers to encounter future protagonists before their own romances begin. The Buchanans are successful, opinionated, and intensely loyal, creating a network of lawyers, investigators, agents, and family members who respond collectively whenever one of their circle is threatened.
Mercy expands that network through attorney Theo Buchanan and surgeon Michelle Renard. Michelle’s family and Louisiana community introduce the Renards, whose connections become particularly important in Killjoy. The series continues to grow through friendships and marriages rather than through a single uninterrupted conspiracy. Kate MacKenna’s relationship with Dylan Buchanan in Slow Burn brings the MacKenna family into the established circle, while later novels draw additional siblings, friends, and professional associates into new cases.
Each book generally presents a separate couple and a self-contained threat. A reader can follow most individual novels without knowing every earlier investigation, but familiarity with the recurring families adds warmth and context. Weddings, conversations, sibling rivalries, professional favors, and references to previous relationships show how the community changes over time. Characters who once appeared as protective brothers, skeptical friends, or background investigators eventually receive stories that reveal different sides of their personalities.
The suspense varies considerably across the series. Some novels center on FBI investigations and serial predators, while others involve corporate crime, embezzlement, political influence, extortion, cybercrime, or danger connected to inherited property. Garwood typically places an accomplished woman in a situation that exposes both her independence and her vulnerability. Her heroines include doctors, entrepreneurs, computer specialists, filmmakers, attorneys, and musicians. They may require protection from an immediate threat, but they are rarely passive participants in their own survival.
The romantic pattern depends on contrast. Garwood’s heroes are often trained to assess risk, control an operation, and keep emotion separate from duty. The women they protect resist being managed, question their assumptions, and bring disorder into carefully regulated lives. Family members frequently recognize the attraction before the couple admits it, providing comedy and emotional pressure alongside the criminal plot.
The series is variously labelled Buchanan-Renard, Buchanan/FBI, or Buchanan-Renard-MacKenna. These names describe the same broad contemporary continuity rather than separate sequences. Not every protagonist belongs to one of the three named families, and the later books become increasingly independent, but personal and professional links keep them within the same world.
Grace Under Fire, featuring Michael Buchanan and Isabel MacKenna, became the final installment and Garwood’s last published novel. It brings two of the series’ central family lines together while preserving the balance that defines the entire sequence: immediate danger, persistent attraction, protective relatives, and two strong-willed people discovering that trust is more difficult—and more important—than physical survival.
