Emma and Galen's kingdom—and their love—is threatened by long-lost Syrena in the brilliant conclusion to Anna Banks' bestselling trilogy.

Emma, half human and half Syrena, and her Syrena love, Galen, need time together—alone. Away from the kingdoms of Poseidon and Triton. Emma's grandfather, the Poseidon king, suggests the two visit a small town called Neptune.

Neptune is home to both Syrena and Half-Breeds alike. But Emma and Galen didn't sign up to be peacemakers between the ocean and the land-dwelling, freshwater Syrena. They didn't bargain for meeting a charming Half-Breed named Reed, who can barely disguise his feelings for Emma. And they especially didn't expect to find themselves in the middle of a power struggle that threatens not only their love but their ocean kingdoms.

In this stunning conclusion to her bestselling Syrena Legacy, Anna Banks thrills fans with more action and romance than ever.
