The second in a series of tales about the clans of fearless Vikings and mystical Sirens who face each other in a neverending battle over their greatest source of life: the sea. A young merman struggles to master his powers over magic-and to keep secret a forbidden relationship. A Viking convinced that a mermaid murdered his eldest son seeks revenge against the world beneath the waves. Two races at war, their battles savage, bloody, and ultimately tragic-for their fates are intertwined far more than either side realizes. (W) Dave Bardin & Various (A) Francesco Trifogli & Various
