Four years ago, Crystal White fell in love with Llyr, a prince of the magical mer colony living off the coast of Starfish Island. For one summer, he enchanted her with stories of jeweled palaces and underwater gardens, but then he left, returning beneath the waves with her heart in tow.
Now, graduated and with no job in sight, Crystal is forced to go back to the island she thought she had left in the past. By the sea again, she realizes she is far from over her first love, and when an opportunity arises to contact the merfolk, Crystal can’t resist.
Once more with the mer, Crystal is forced to come to terms with the fact that Llyr has moved on, and also with her own magical secret that has endangered her life, his throne, and every mer kingdom. Working against all odds, she has to try to save the people she has come to love and—if she can—rekindle the romance of her first summer on Starfish Island.
