When Emma's grandfather, the Poseidon king, suggests she and her Syrena love, Galen, visit a small town called Neptune, they find themselves in the middle of a power struggle that threatens not only their love but their ocean kingdoms.
Half-human, half-Syrena Emma and her full Syrena lover Galen take time away together in a small town called Neptune, under the sea. Both Syrena and Half-Breeds live together there, so it seems perfect--until another man tries to move in on Emma, and the two find themselves in the midst of a power struggle that threatens both their kingdoms.
