Gudrun Osvifsdottir, Prophetic Dreams' willful protagonist, is not only renowned for her beauty and intelligence, she is also thought to be the best catch in the district. Headstrong and spoiled by her adoring parents, she yearns for female friendship. Growing up on a tenth-century farm in an isolated region in Iceland, she cannot understand why the few girls living in her district have persistently avoided her. On the other hand, all eligible males compete for her recognition. Basking under their high-spirited attentiveness, she soon convinces herself the only reason she is ignored by her peers is because they are jealous of all the attention bestowed on her by the male population. This protective shield may guard her growing ego, but it soon sets her further apart from the other females that live in her area.

Pagan Icelanders believed dreams foretold the future. Haunted by nightmares, her parents enlist the nation's most famous seer to translate them for her. A melodramatic young girl, her emotions are soon stirred into a frenzy by his interpretation.

As foreshadowed, tragedies do occur. One death is even rumoured to be the result of black magic. Later, a misunderstanding and silent accusations create a slow pyroclastic flow of vengeance. Will the stakes be too high for our protagonist? Will she lose the one man she admires and respects more than any other?
