In a cozy library in the southern reaches of the empire of Rasena Valentis, five seers gather one night. They have all had the same horrifying vision: an endless multitude of giants will appear on the morning of a sunless dawn, burning the sky and shaking the pillars of heaven. One woman will stand against them.
For four of the seers, the prophecy is a terrifying and bewildering vision of the future. But for their leader Nensela, it is an answered prayer … and her worst nightmare come true. The giants come from no land in the Known World, and the power they wield is one that sorcerers could only covet. Their insidious allies slay anyone who learns of the giants — and may even have the power to interdict the gods themselves.
Now, Nensela must gather to her side unlikely allies of her own: Edana Nuriel, an orphan whose rise to success reveals a sinister volley in their war … Elisabet Bessa Philomelos, an aspiring playwright whose very words may sow seeds that bear fruit in deeds … and from distant Lyrcania, land of gunpowder and artificers comes Alia Ironwing, a priestess carefully trained by dryads to serve as their last, best chance of victory.
The imperial astronomers can offer only one hope: They have one thousand days until the sunless dawn.
One thousand days to stop a prophecy.
One thousand days to save the world.
Or see hell unleashed.
