Special Agent Assignments Books in Order

Special Agent Assignments is one of Liz Johnson's earlier romantic suspense series, and you can see the pieces of her later work taking shape inside it. These books are lean, high-pressure stories about people under protection, federal investigations, and the question of who you can trust when danger is already close. The local titles The Disappearance of Devyn Keating and The Hunting of Heather Sloan were originally published as Vanishing Act and Code of Justice, so readers may see both sets of names attached to the series.

The first book, The Kidnapping of Kenzie Thorn, throws readers straight into trouble. Kenzie is teaching a GED class in prison when one of her students turns out to be an undercover FBI agent. Myles is there because someone wants her dead, and once the threat breaks open, the only way to protect her is to get her out fast. That setup tells you what kind of series this is: close quarters, shifting identities, and a hero and heroine who do not have the luxury of taking things slowly.

The second book, The Disappearance of Devyn Keating, leans even harder into the hidden-identity angle. A young woman has already rebuilt her life under another name after witnessing her father's murder. She is trying to keep her head down in a small Colorado town when an FBI agent tracks her down, just as the men hunting her start closing the distance. The tension comes not only from the chase, but from the fact that being found by the good guys still feels like being found.

Then The Hunting of Heather Sloan shifts into investigation mode. Heather survives a helicopter crash that kills her sister, and she refuses to accept that it was an accident. Working with deputy Jeremy Latham, she starts following a trail that points toward murder and organized crime. Compared with the first two books, this one is a little more rooted in solving a case, but the emotional engine is the same: grief, danger, and two people learning to rely on each other when the risk keeps rising.

Names change. Loyalties get tested.

What links the series best is its pace and tone. These are compact suspense novels with clean romance, faith threaded through the story, and protagonists who are often isolated from normal support systems. The settings shift from prison corridors to small-town hiding places to crash investigations, but the feeling stays consistent. Johnson likes smart heroines, protective heroes, and plots that force both of them to act before they are emotionally ready. If that mix works for you, this series is an easy place to start with her suspense backlist.
