book four
In the watery depths of Lazurite Bay, a prince has vanished—and war is brewing…
Twin sisters Niamh and Naia Callaghan find themselves thrust into supernatural conflict when they discover a dying mermaid on Thunder Island. Rising tensions between her clan and the water fae have made the mermaids prime suspects in the disappearance of the crown prince, with war looming on the horizon.
The fae king and queen enlist the help of the prince's cousin—a cunning fairy with a secret double life—to find him before it’s too late. As a daring rescue mission unfolds, the fates of the fae, mermaids, and Callaghan twins intertwine, revealing a dark web of political intrigue, betrayal, and forbidden love.
With pressure mounting to keep secrets hidden from human eyes, alliances will be tested, and the true cost of loyalty will emerge in a world where trust is a fragile illusion.
