Shattered Sea is a young adult fantasy series written by the British author Joe Abercrombie.

Yarvi is betrothed to Isriun, his cousin and the fiancée of his dead brother, to shore up his political station.

While on a raid against the Vanstermen who killed his father, Yarvi is betrayed by his uncle Odem, who usurps the crown.

Yarvi reveals his identity and promises to make Gettland a vassal state of Vansterland in exchange for passage home.

The swordsman Nobody is revealed to be Uthil, Odem's and Uthrik's older brother who had previously been captured by slavers.

Yarvi realizes that Mother Gundring and Odem had conspired with the High King and his minister Grandmother Wexen.

Yarvi travels with Brand, Thorn, and a host of warriors to seek out allies for Gettland in the political conflict with the High King and Grandmother Wexen.

Thorn saves the new empress Vialine from an assassination attempt, which allows Gettland to form an alliance with the Empire.

As Leithlin’s chosen shield, Thorn stands for Uthil and fights Grom in single combat.

Gorm decides to defy Grandmother Wexen and forge an alliance with Gettland against the High King.

Brand learns that Yarvi poisoned Uthil in order to manipulate the duel between Grom and Thorn.

Bright Yilling, the champion of Grandmother Wexen, conquers Throvenland and kills King Fynn, and ally to Uthil and From.

Father Yarvi and his apprentice Koll reunite with Skifr, who tells them that Grandmother Wexen killed her family.

In Bail's Point, Bright Yilling kills Uthil in a duel and reveals that there is a traitor from Gettland who feeds him informations.

Father Yarvi, Koll, and Skifr enter the forbidden elf-city of Strokom and steal weapons.

Yarvi, now the head of the ministry, attempts to annex Throvenland and marry Skara to his younger half-brother.

(He betrayed the alliance in order to ensure that Gettland would never sue for peace and threaten his desire for vengeance against the High King and Grandmother Wexen.)

Koll abandons Yarvi and the ministry, choosing to stay with Rin in Queen Skara's service.
