Abysmal

(Book 2 of the Abyssal Series) With his best friend's life in the hands of the most ruthless merman in the seven seas, King Marius the Conqueror, Kai…is running out of time. To stand a chance at saving him, Kai must master the catastrophic power he inherited-but controlling it may cost him his own soul. Kai's hatred for Marius is all-consuming, but so too are the dangerous, conflicting emotions that churn beneath the surface. For beneath the animosity, something darker stirs-something that threatens to unravel everything he believes about himself and the merman he once swore to destroy. Guided by the elusive Spirit of the Sea, Kai plunges into forbidden magic, desperate to turn the tides of war. When the moment of reckoning comes, he traps Marius in a deadly spell, believing he has finally turned the tables on his nemesis. But he soon learns that Marius's power runs deeper than he ever imagined-and that the Spirit of the Sea may not be the ally he thought. As the ocean is consumed by the spreading Dark Zones, a void devouring everything in its path, Kai faces an impossible choice: abandon his thirst for vengeance to save the world he swore to protect, or let his hatred consume him. With new enemies rising and Marius revealing a past more fractured than Kai could have imagined, the line between enemy and ally begins to blur. With treachery closing in on all sides, one question remains: Can the ocean's most feared tyrant become the ally Kai needs to survive? Read more
