Surlalune Blog has an article on a book that you might find interesting. I'll do a review as soon as I've read it.
Inspired by the beloved classic The Little Mermaid, THE MERMAID'S PENDANT is a modern fairy tale about growing up and discovering who you are -- and what you believe in. At times lyrical, this novel is a fantastic journey filled with magic, myth, romance, and adventure. Four years after John Wilkerson claims the mermaid Tamarind for his wife, they have an idyllic marriage that depends on a talisman that she crafted on their island paradise. But Tamarind learns a painful truth: it takes more than legs to live on land and more than magic to sustain a bond. When the talisman breaks, she and John are forced to rely on themselves instead of magic. Three wise women play key roles in the young lovers' journey to mature love. Ana, Tamarind's aging mentor, casts spells and performs seductions to keep the lovers apart. Valerie, an ex-pat jewelry maker cum fairy godmother, works her own magic to bring them together. Lucy, their widowed neighbor, grounds the couple in the realities of marriage, parenting, and family. THE MERMAID'S PENDANT is a story for anyone who has ever believed in the transforming power of love.
