Amy's family (especially her step dad) is driving her nuts, so a summer in Wildwood NJ away from them is just what she needs. And when she discovers the swimmers at Mermaid Park, she knows that she has found her calling. During the summer she learns to deal with the anger she feels towards her family and how to transcend it as a "mermaid."
I wanted to like this novel very much, but it was all over the place. It took nearly 100 pages just to develop a sense of the characters and their relationships to each other. In the end, I didn't find myself terribly moved by any of them.
