If you loved how Modo takes on assignments from Mr. Socrates—slipping into enemy strongholds and outwitting the Clockwork Guild—Boneshaker gives you that same propulsive, objective-driven momentum. Briar Wilkes plunges into a walled, toxic Seattle to rescue her son, navigating rival factions, deadly streets, and clanking contraptions. The way she assembles allies like Captain Cly and Lucy O’Gunning to penetrate hostile territory will scratch that itch for tightly focused, perilous missions that keep you racing through chapters.

Remember Modo’s sprinting rooftop pursuits in Victorian London and those frantic getaways with Octavia? Airborn delivers that same headlong velocity—only at ten thousand feet. Cabin boy Matt Cruse faces sky pirates, midair battles, and white-knuckle rescues aboard the airship Aurora, with one narrow escape after another. You’ll get the same pulse of cliffhangers and swashbuckling close calls that made Modo’s spycraft so addictive.

If the automata, shadow societies, and foggy London streets hooked you—along with Modo’s talent for disguise—Leviathan will sweep you into an even bigger tapestry. Deryn Sharp masquerades as a boy to serve aboard the living airship Leviathan, while Alek flees in clanking walkers—Darwinist beasts vs. Clanker machines. The mash-up of biological wonders, clockwork tech, and undercover roles gives you that same textured alt-history you explored with Modo and Octavia.

Modo’s journey—from Mr. Socrates’s secret tutelage to a confident partner beside Octavia—mirrors the satisfying growth arc in The Thief. Gen is pressed into a dangerous heist by the Magus, and as the journey unfolds, his wit, nerve, and hidden talents sharpen in surprising ways. If you liked seeing Modo wrestle with identity and self-worth while learning to outthink his opponents, Gen’s evolution and clever reversals will hit that same sweet spot.

The Clockwork Guild’s uncanny devices and Modo’s encounters with masked inventors set the stage for Fever Crumb. In a proto–London, Fever is raised by the Order of Engineers, where relic machines and half-remembered sciences are treated like occult knowledge. As she uncovers buried technologies and conspiracies beneath the city, you’ll get that same tingle of wonder and menace that comes when gears, circuits, and secrets blur into something almost mystical.
