I sometimes write reference pieces for myself so I can give some context to myself about what I’m writing. Those pieces usually are never seen by others, but they’re useful for me, and they make a better book for everyone else. This is one of those pieces. In the book, humans get around space via “The Flow” — a “metacosmological multidimensional space” that’s not of this universe but lets people get around in it at multiples of the speed of light. I decided I needed to give The Flow an origin story, as well as understand how people discovered it, so I wrote this piece for myself, which I am sharing with you now.

The first novel of a new space-opera sequence set in an all-new universe by the Hugo Award-winning, New York Times-bestselling author of Redshirts and Old Man's War. Our universe is ruled by physics and faster than light travel is not possible—until the discovery of The Flow, an extra-dimensional field we can access at certain points in space-time that transport us to other worlds, around other stars. Humanity flows away from Earth, into space, and in time forgets our home world and creates a new empire, the Interdependency, whose ethos requires that no one human outpost can survive without the others. It’s a hedge against interstellar war—and a system of control for the rulers of the empire. The Flow is eternal—but it is not static. Just as a river changes course, The Flow changes as well, cutting off worlds from the rest of humanity. When it’s discovered that The Flow is moving, possibly cutting off all human worlds from faster than light travel forever, three individuals—a scientist, a starship captain and the Empress of the Interdependency—are in a race against time to discover what, if anything, can be salvaged from an interstellar empire on the brink of collapse.

The Consuming Fire―the sequel to the 2018 Hugo Award Best Novel finalist and 2018 Locus Award-winning The Collapsing Empire―an epic space-opera novel in the bestselling Interdependency series, from New York Times bestselling author John Scalzi The Interdependency―humanity’s interstellar empire―is on the verge of collapse. The extra-dimensional conduit that makes travel between the stars possible is disappearing, leaving entire systems and human civilizations stranded. Emperox Grayland II of the Interdependency is ready to take desperate measures to help ensure the survival of billions. But arrayed before her are those who believe the collapse of the Flow is a myth―or at the very least an opportunity to an ascension to power. While Grayland prepares for disaster, others are preparing for a civil war. A war that will take place in the halls of power, the markets of business and the altars of worship as much as it will between spaceships and battlefields. The Emperox and her allies are smart and resourceful, as are her enemies. Nothing about this will be easy... and all of humanity will be caught in its consuming fire.

The collapse of The Flow, the interstellar pathway between the planets of the Interdependency, has accelerated. Entire star systems—and billions of people—are becoming cut off from the rest of human civilization. This collapse was foretold through scientific prediction… and yet, even as the evidence is obvious and insurmountable, many still try to rationalize, delay and profit from, these final days of one of the greatest empires humanity has ever known. Emperox Grayland II has finally wrested control of her empire from those who oppose her and who deny the reality of this collapse. But “control” is a slippery thing, and even as Grayland strives to save as many of her people from impoverished isolation, the forces opposing her rule will make a final, desperate push to topple her from her throne and power, by any means necessary. Grayland and her thinning list of allies must use every tool at their disposal to save themselves, and all of humanity. And yet it may not be enough. Will Grayland become the savior of her civilization… or the last emperox to wear the crown?
