The enchanting first tale in the New York Times best-selling series is now available in a beautiful twentieth-anniversary edition poised to captivate a new generation.

For as long as she can remember, twelve-year-old Emily Windsnap has lived on a boat. And, oddly enough, for just as long, her mother has anxiously kept Emily away from the water. But when Mom finally agrees to let her take swimming lessons, Emily makes a startling discovery--about her own identity, the mysterious father she’s never met, and the thrilling possibilities and perils shimmering deep below the water’s surface. In a lovely twentieth-anniversary edition of the spellbinding fantasy about family secrets, loyal friendship, and the convention-defying power of love, New York Times best-selling author Liz Kessler lures us into a glorious undersea world where mermaids study shipwrecks at school and Neptune rules with an iron trident. This deluxe unjacketed hardcover features a ribbon bookmark, decorative stained edges, an author’s note, facts about mermaids, and a personality quiz to reveal what kind of sea creature the reader might be.
