Three teen's grow up together as practically siblings, each with an amazing story of how they came to their adoptive family.  Maren was found inside of a conch shell during the middle of an October storm, on a mountain in Pennsylvania.  Clare was brought by a stork to Auntie Verity.  And O'Neill was found beneath an apple tree by a priest that was mourning the death of his brother.  O'Neill had a birthmark exactly the same as the priest's brother.  O'Neill, as a boy, was raised by the traveling merchant Ezra Scarff, who is Auntie's sweetheart, and visits as often as he can.  This of course sounds amazing; however, Auntie is part fairy and so can't lie.   Plus around her 16th birthday Maren starts turning into a mermaid.  And so she needs to get to the ocean to be with her merfolk family and take her place as a mermaid  princess.  Auntie can not leave the mountain, due to a curse placed on her, and so they must wait until Scarff and O'Neill can make it back to the mountain.  Scarff gets very sick and has to be nursed back to health by gypsies before he is well enough to travel to the mountain and so Maren is a full mermaid before they can start on their way.  Also even after he gets there he is too ill to make to journey quickly and so Clare and O'Neill must transport Maren to the ocean.
