The Unmaking is erasing the realm. It does not burn villages or leave ruins. It removes them so completely that even the memory of what stood there is gone. The only defence is the unfinished Bone Throne that Empress Sabra inherits from her mother, whose remains are already built into the seat. To strengthen it she must set powerful bones taken from saints, beasts, rulers and enemies, and each one she sets demands a matching bone of her own.

When she gives her fingers, the throne takes her touch. When she gives her legs, she can no longer walk away. Sabra believes that anyone willing to suffer personally has earned the right to decide what others must sacrifice, and that belief drives her toward the Marrow Court, a deathless aristocracy that owns the trade in the dead. Her consort Corin and her younger sibling Nol refuse to be things she saves without asking. And the true price of the throne is worse than any of them guess.

Book One: The Unmade Queen

Sabra sets bone after bone into the throne, paying a piece of her own body for each, until she has completed enough of it to hold the tide. Then she learns what finishing it will truly cost: to sit forever beside her mother, and to leave a second seat waiting, shaped for the next of her bloodline.

Book Two: A Crown of Broken Marrow

Ruling from inside her own coffin, Sabra wages war on the Marrow Court to undo the charter that handed them the realm's dead. But the throne has begun charging a second price, eating her memories one at a time, and Corin becomes the keeper of their marriage, telling her the story of their life each night so she can remember who she is.

Book Three: The Unmade Empire

The tide returns wearing the faces of every empress the throne consumed, and Sabra learns it was never an invader but the robbed dead trying to come home. The ending cannot be commanded. It can only be given, freely, by everyone she loves, and it costs exactly what it was always going to cost.
