Deep Betrayal is no bright Disney mermaid tale of love and devotion. Anne Greenwood Brown spins a sinuous tale of romance and the bonds of family. Her sequel, Deep Betrayal, is more tame than Lies Beneath, but without losing the important connections between Calder, Lily and her Father. The change of perspective from Lily to Calder also helps to continue the story, but gives Deep Betrayal new twists and turns to further the reader's interest.
