Paige Mahoney has eluded death again. Snatched from the jaws of captivity and sent to a safe house in the Scion Citadel of Paris, she finds herself caught between factions that seek Scion's downfall and those who would kill to protect the puppet empire.

The mysterious Domino Program has plans for Paige, but she has ambitions of her own in this new citadel. With Arcturus at her side, she embarks on an adventure that will lead her from the catacombs of Paris to the glittering hallways of Versailles.

As Scion widens its bounds and the free world trembles in its shadow, Paige strives to understand her bond with Arcturus, which grows stronger by the day. But there are those who know the revolution began with them--and could end with them . . .

With its intricate worldbuilding, slow burn romance, and "complex, ever evolving, scrappy yet touching" (NPR) heroine, the Bone Season series shows Samantha Shannon at the height of her considerable powers.
