Caught in a curse by a coven of witches, seventeen-year-old Greer O' Donnell is turned into a mermaid for the next two hundred and fifty years. She must grant wishes to all the sailors she meets. But when she washes up on the shores of Lake Petapanke, she meets Duff Brogan, the man who could break a witch's curse. Abandoned by his family, Duff Brogan burned through almost twenty foster homes before his 18th birthday. After discharge from the Army, Duff bought a small cottage on the lake and resolved to be alone the rest of his life. But when a mermaid approaches him in the middle of a January storm, he can't let her go and refuses to make his wishes. Can Greer convince Duff to fall in love with her, thus breaking the curse? Will Duff open his heart to Greer? Or will he unknowingly release her back into the water to serve the balance of her curse's term?
