Sixth World Books in Order

The Sixth World is a post-apocalyptic fantasy series, but it starts from a very grounded question: what does daily life look like after the world ends and the old stories turn out to be real? In Rebecca Roanhorse's version of the future, climate disaster brings the Big Water, flooding huge parts of the planet. Dinétah, the homeland of the Navajo Nation, survives and changes. Magic returns. So do heroes, gods, and monsters. Trail of Lightning opens inside that new world, where people still worry about trade, family, and water, even as something hungry waits in the dark.

It is fast, violent, and very human.

The series follows Maggie Hoskie, a Diné monster hunter with supernatural gifts and a lot of pain she would rather outrun than explain. Maggie is tough, funny when she wants to be, and not built for easy trust. Her main foil and ally is Kai Arviso, an unconventional medicine man whose warmth, charm, and spiritual skill make him a very different kind of fighter. Their partnership gives the books much of their energy. They bicker, protect each other, and keep running into questions neither of them can solve with a knife or a spell.

The setting matters as much as the monsters do. Dinétah is not just a backdrop for action scenes. It is a living place shaped by clan ties, ceremony, obligation, memory, and the practical business of getting through the day after collapse. Roanhorse mixes chapter houses, trading posts, walls, sheep, guns, old highways, and broken tech with witches, tricksters, gods, and creatures pulled from story into flesh. That blend gives the books their particular feel. The world is battered, but it is not empty. People are still making homes, raising children, arguing over policy, and trying to imagine a future.

Nothing stays safely in legend for long.

In Trail of Lightning, a missing girl case pulls Maggie and Kai into a wider mystery involving dark witchcraft and Maggie's own past. Storm of Locusts widens the lens. The danger is no longer one town or one monster, but a cult, a prophet called the White Locust, and the terrifying world beyond Dinétah's walls. Later, the novella River of Bones returns to this setting from Kai's perspective and pushes the story into older wounds and dangerous family ties. Across these books, Roanhorse keeps the tension moving while asking bigger questions about trust, community, faith, and what survival is supposed to mean once the emergency becomes everyday life.

If you like fantasy with monster hunting, sharp banter, and high stakes, this series delivers that. If you want something more than monster hunting, it has that too. The real pull of The Sixth World is the way Roanhorse balances action with aftermath. Every fight leaves a mark. Every alliance costs something. And every time Maggie tries to go it alone, the books remind her, and us, that even the toughest survivor has to decide who she belongs to.
