Keeping secrets is my job. Uncovering the truth is his.


As a highly trained operative in a family of spies, I learned a a long time ago what happens when you fall in love and reveal yourself to the one person who should accept you most. I lost everything. Now, I keep my head down, do the work, and keep my mouth shut. Trusting no one is the only way to survive in this world.


Special Agent is my title. Leif McAllister is my name. “Dusty” is what everyone calls me. Been told I can talk a stone to dust, but that kind of verbal fortitude makes my job easier. People trust an open book. Even if that book is filled with lies. Most people, anyway. I thought Gracie Parish was my in to uncover her family’s illegal activities, but she won’t budge. No problem. I’ll use everything I’ve got—fair, unfair, and so-good-it’s-wrong—to penetrate her defenses and prove my case.

Even as the red-hot attraction between Dusty and Gracie heats up, his investigation ignites a deadly new threat. They’ll have to decide quickly how far they can trust each other, because now it’s not just Gracie’s vigilante lifestyle in jeopardy. It’s her life.

Praise for Reckless Grace (Spy Makers Guild Book 2)

“Stewart’s badass romantic suspense series adds a high-octane installment with this satisfying roller-coaster ride. Computer whiz and dance club owner Gracie was adopted as a child by the Parish family, a large and ever-growing group of benevolent, mostly female vigilantes. She has been raised to fight for truth and justice, but some days she’s just tired of it. FBI agent Leif “Dusty” McAllister has been on the Parish case ever since a frustrated Gracie revealed some of her family’s actions in an anonymous email. Convinced that Mukta Parish, the family matriarch, is conscripting unwilling children into her personal army, Dusty plans to infiltrate the group through feisty Gracie—but then he falls in love with her. Very little is as it seems in this intricately plotted novel. Stewart skillfully drags a number of red herrings out regarding a would-be killer, delivering an unexpected ending. Enjoyable all on its own, the novel drops tantalizing story lines for future books in the series and neatly builds upon the prior installment. Stewart’s talent shines in this suspenseful story.” Publishers Weekly 

“The second installment of the sexy and suspenseful series pits a vigilante computer whiz against an FBI agent with a grudge.

Bullets are flying when Gracie Parish and Leif “Dusty” McAllister meet in the middle of a covert operation to dismantle a sex-slave operation in Mexico. The attraction is instant, but the more they get to know one another, the wider the gap between them seems. Adopted as a child by the Parish family and raised to fight injustice…, Gracie is conflicted about the heavy price exacted by the vigilante lifestyle. She’s already lost a husband and child to Parish family secrets and wonders what life would be like if her front as a club owner were really her full-time profession. Dusty’s abusive childhood at the hands of a cult leader did not endear secret groups to him. He wants to take the Parish clan down, but as he comes to know and respect his “helpful asset,” he finds himself teetering on the “shaky edge of undercover morality.” Muñoz Stewart (I Am Justice, 2018, etc.) skillfully questions the difference between loyalty and subservience, enculturation and indoctrination as she weaves a tender romance around a thrill ride of a plot that will keep readers guessing until the final pages.

Layered personalities, shifting motivations, and a smart, twisty plot push this thrilling romantic suspense series into high gear.” Kirkus Reviews

THE PRICE OF GRACE is Diane Munoz Stewart at her best. This is action-packed, thought-provoking, sexy, with a lot of twists and turns, and at times just fun.” Fresh Fiction

“A vigilante family, a cache of secrets, a monumental threat, and an overpowering love. The dynamics in [Undercover] Grace are instant and intense and hot. The pages will burn your fingers.” Patricia Gussin, New York Times Best-selling author of Come Home

“Diana Munoz Stewart knows how to deliver what a reader wants.  A brilliant and complicated heroine, an equally flawed hero, and tight suspense that unfurls almost lyrically. Poignant in places, nail-biting in others, there’s plenty of sizzle and emotional clout.  An electrifying ride.”
