Vinland Saga

From Kodansha:
As a child, Thorfinn sat at the feet of the great Leif Ericson and thrilled to wild tales of a land far to the west. But his youthful fantasies were shattered by a mercenary raid. Raised by the Vikings who murdered his family, Thorfinn became a terrifying warrior, forever seeking to kill the band’s leader, Askeladd, and avenge his father. Sustaining Thorfinn through his ordeal are his pride in his family and his dreams of a fertile westward land, a land without war or slavery. The land Leif called Vinland.
