The Shattered Sea Trilogy by Joe Abercrombie

Set in a harsh, Viking-flavored world strewn with the relics of a lost civilization, this trilogy follows a betrayed prince with a withered hand who survives slavery to become a master of statecraft, a fierce young warrior striving for glory in a society that scorns her, and a conflicted soldier seeking honor as their paths converge through perilous voyages, courtly intrigue, and escalating war. Their intertwined journeys explore the price of power, the ambiguity of heroism, and the value of wit over brute force, while buried secrets and the ambitions of a rising High King threaten to reshape the balance of the Shattered Sea.
