Susanna and the Spy Books in Order

The Susanna and the Spy series is a Regency-set adventure that blends manners with espionage. On the surface you get the usual ingredients of the era, country houses, London parties, polite conversations, and the constant pressure to behave. Underneath, the books run on secrets: coded messages, divided loyalties, and the messy reality of the Napoleonic Wars. Expect plots built around information, forged papers, and small choices that can shift much larger outcomes.

Susanna is the kind of heroine society expects to be quiet and compliant. The fun of the series is watching her discover, sometimes the hard way, that she’s smarter and tougher than the world gives her credit for. She learns how to read a room, how to spot when someone is lying, and how to use the limits placed on women as a kind of camouflage.

She has to learn to lie well, fast.

Susanna and the Spy drops her into a situation where being observant is not just useful, it’s survival. A chance encounter pulls her toward a larger plot, and once she understands what’s at stake, she can’t simply step back into her old life. She ends up working alongside a professional agent, but she has to decide how much of herself she’s willing to risk. The story balances suspense with the small details of daily existence, what can be said aloud, what has to be hidden, and what happens when you trust the wrong person.

In London Calling, the stage widens. London is louder, sharper, and more dangerous, and the risks of being seen in the wrong place with the wrong person increase. The social world becomes both playground and battlefield, and Susanna’s choices start to affect more than her own future. The book keeps the focus on character and tension rather than battlefield action, which helps the stakes feel personal.

In these books, a dance card can be cover and a compliment can be a code.

If you’re deciding how to read the series, starting with Susanna and the Spy is the best move because it sets up Susanna’s skills, relationships, and the kind of trouble she’s likely to attract. From there, the sequel builds naturally, taking what Susanna learned and testing it in a more demanding setting. Expect romance, danger that stays mostly offstage but always present, and a heroine who grows more confident each time the story asks her to choose between safety and doing the right thing.
