Sirens of the Norse Sea Vol. 2

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.
