Inventor's Secret Books in Order

The Inventor's Secret takes Andrea Cremer away from werewolves and into something metal, smoky, and political. The series is set in an alternate nineteenth-century North America where the Revolutionary War never happened and the British Empire kept expanding. That one change gives the books their whole mood. The world runs on labor, class rules, and towering machineworks that feel both impressive and cruel.

At the center is Charlotte, a teenage refugee who has grown up on the edge of that empire with a small band of other young survivors. They steal food when they have to, stay mobile, and know that getting caught can mean being dragged into forced labor. When a new exile arrives with no memory and too many dangerous secrets, Charlotte's already fragile world gets pulled into something much bigger than day-to-day survival.

This series is adventure first, but it is not lightweight about its politics. The question is not only whether the empire is brutal. It clearly is. The harder question is what resistance looks like when rebels are secretive, divided, and capable of ugly choices themselves. As Charlotte moves from hiding to action, she has to sort out who deserves her trust and what kind of future is really worth fighting for.

New Orleans becomes a big part of that story. So do river routes, shadowy tunnels, bayou corners, smugglers, pirates, and people who live by their wits. The books have a wider travel feel than Nightshade. Instead of being anchored to one cloistered magical society, they keep pushing outward into markets, docks, camps, and underground networks, which helps the world feel restless and alive.

Gears matter here, but people matter more.

Across The Inventor's Secret, The Conjurer's Riddle, and The Turncoat's Gambit, the stakes keep tightening around Charlotte's loyalties. She has family history tied to the rebellion, friendships tested by fear, and a growing sense that slogans about freedom can hide their own kind of control. That gives the trilogy a nice pull. You are not only waiting to see who wins. You are waiting to see what Charlotte decides is worth becoming.

The tone lands somewhere between steampunk adventure and young adult resistance story. There are inventions, escapes, betrayals, and chase scenes, but also a strong thread of found family and moral uncertainty. If you like alternate history that asks how a different America might have been built, and who would have paid the price, this series gives you that question inside a fast-moving story.
