Vikings, the world\'s fiercest warriors and greatest sailors rule the land. But the sea has never been so easy to claim, for another creature dwells within it: the Siren. For generations, Viking clans have had to face Siren tribes: a constant battle between cunning and brute strength, and charm and sorcery, with the vast ocean in between. In each book in the series, their paths intersect, for better or for worse.
