Faster than light travel isn’t possible. Luckily for the citizens of the Interdependency there is The Flow, the unexplained something, kind of like a river, that allows travel between the stars. Until now, that is. The Flow is failing. Not common knowledge, to be sure, but a few know that things are about to get very interesting very soon. But what to do with that knowledge? Prepare humanity for the collapse … or capitalize on it? Politics, machinations, nobility … choices. The Interdependency is an empire, and like the name suggests, its constituents are quite dependent on each other. In fact, there’s really only one currently-reachable planet that can sustain itself, and that’s the appropriately named End. End is about to become the center of the known universe. I loved this novel and can’t wait for the next installment. Oh, and you’re gonna love Kiva. Even if she kills you.
— Guest Reviewer Patrick HeffernanOur universe is ruled by physics, and faster-than-light travel is not possible - until the discovery of The Flow, an extradimensional field we can access at certain points in space-time that transports 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.
