The Half-Drowned King is historical fiction, set in Norway during the early years—and early campaigns—of Harald Fair-hair, whom later history remembers as the first king of Norway.

Hartsuyker chooses not to focus on Harald himself, but instead on two siblings from a coastal farm, Ragnvald Eysteinsson and his sister Svanhild.
