‘Half the World’ is the sequel to ‘Half a King’, set some time after the conclusion to that book, and focusing on different characters. In this book, we focus on the young warriors-in-training Brand and Thorn, and the events that keep them from taking their place on a raid. Soon, they end up on Yarvi’s ship, as he goes on a journey to make an alliance to save Gettland from the coming war with the High King.
