From publisher blurb:
Scandinavia may no longer be the lands of the Vikings, but some of the old magic still survives. In barrow mounds, ancient guardians and buried kings wait, ready to strike against those who would invade their domain and steal their riches.
And from the frozen past comes the jotuns, an ancient race of monsters who believe the land was stolen from them by humans and who seek to destroy the modern world in order to rebuild it to their liking.
