Emma and Galen are desperately in love, but they can't be together. Emma is half-mermaid - a freak in the human world and an abomination in the Syrena realm below - and Galen is a gorgeous Syrena from the House of Triton, god of the sea. And if the Syrena discover that Emma's a Half-Breed, she could be put to her death.
But a tense situation worsens when Emma's mother - an estranged princess from the House of Poseidon - returns to the underwater world to protect her...and turns the two kingdoms, Poseidon and Triton, against one another.
All Emma and Galen want is to be together - but how long can their relationship last when two very different worlds are determined to tear them apart?
