The Thief

by Robin McKinley

McKinley shares Turner's gift for embedding political intrigue within adventure—your protagonist here is similarly caught between worlds and loyalties, discovering their own agency through a dangerous quest. The slow-burn revelation of what the main character is truly capable of mirrors that satisfying twist you just experienced, where everything clicks into place retroactively.

by George MacDonald

This one's quieter than The Thief—less heist, more court politics—but Addison does something Turner also does brilliantly: she trusts readers to understand complex social hierarchies without spelling them out. Your protagonist must navigate a world where everyone has hidden agendas, and like Gen, he learns to read people as carefully as a thief reads locks.

by Elizabeth Kostova

A departure from fantasy into literary mystery, but Kostova constructs her narrative the way Turner constructs hers—through layers of revelation and unreliable narration that make you want to immediately reread it. The journey across Eastern Europe echoes your road-movie structure, and the obsessive quest for a hidden truth will feel familiar, even if the setting is our world rather than a fantastical one.

by Diana Wynne Jones

Jones writes with the same wry humor Gen displays—her protagonist complains just as much while accomplishing far more than expected. The magic system is genuinely strange rather than explained, and the central relationship between the two leads has that same complex, unspoken dynamic where you're never quite sure what either character actually wants until the very end.

by Scott Lynch

This is the obvious choice I'm recommending anyway because it genuinely earns it—Lynch takes the clever-thief premise and runs it through a heist-story structure with multiple timelines that reveal character motivations the way Turner's twist does. The banter between con artists has that same blend of genuine affection and self-interest that makes Gen's relationships compelling, and the world-building respects your intelligence enough to let you piece things together.
