Expats/Kate Moore Books in Order

Kate Moore seems like the quintessential trailing spouse. When her husband, Dexter, lands a lucrative banking job in Europe, she packs up their lives in Washington, D.C., and moves the family across the Atlantic. To the outside world, she is just another American mother navigating school runs, playdates, and the confusing social etiquette of a foreign country. She appears to be worrying about language barriers and grocery shopping.

But appearances are intentionally deceiving.

Before she was a stay-at-home mom, Kate was a highly trained operative for the CIA. She spent years working deep undercover, managing assets and handling dangerous situations that most people only see in movies. The move to Europe was supposed to be her clean break, a chance to leave the deception behind and finally be honest—or at least as honest as a former spy can be—while raising her two young sons.

The first chapter of her new life takes place in Luxembourg, the setting for The Expats. It is a small, wealthy, and somewhat sleepy city where privacy is paramount and questions are discouraged. Here, Kate struggles with the loss of her identity and the sheer boredom of her new routine. However, her instincts haven't faded. She begins to notice inconsistencies in the lives of the other expatriates she meets.

A chance encounter with another American couple triggers her internal alarm bells.

Kate soon realizes that she isn't the only one pretending to be someone else. The tension in the series comes not just from external threats, but from the quiet, gnawing suspicion that creeps into her daily interactions. The most unsettling realization is that the deception might be coming from inside her own house. Her husband’s job isn't quite what it seems, and the secrets he is keeping could put their entire family in the crosshairs.

The story continues in The Paris Diversion, where the Moores have relocated to the bustling streets of Paris. The pacing shifts here, unfolding over the course of a single, high-stakes day. While Kate tries to maintain the facade of a normal life, a terrorist threat forces her back into the field. She has to rely on the skills she swore to abandon to navigate a complex web of threats that targets everything she loves.

What makes these books stand out is how they ground high-concept espionage in the mundane realities of parenting and marriage. Kate acts as a relatable anchor in a chaotic world. She worries about her children’s safety just as much as she worries about international conspiracies, often blurring the line between a protective mother and a lethal agent. It is a look at how hard it is to truly know the people around you, even when you have been trained to spot a lie from a mile away.
