They built a wall the empire couldn't take. So the empire stopped trying to take it, and started trying to own it.
Kaia Thorne and Cassian Stormwright are married, bonded, and out of places to hide. Two great powers close on their sanctuary at once: one means to cleanse it, one to fold it quietly into the order of things. Both rest on the same six-hundred-year lie, that callers like Kaia are the doom the realm was warned of.
Kaia and Cassian hold the truth that breaks the lie. They have kept it banked, unspoken, waiting for a hearth large enough to set it down in front of.
That hearth is coming. Once a decade the two moons align, the Tideline thins to nothing, and both fleets gather at the failing wall, the one wall a bonded pair can hold by hand, in front of the whole watching world.
To win a future, they will have to spend everything they buried, in the open, together.
The saga of shadow and storm comes to its reckoning.
