"One of the swimmers plunged underwater with a flick of his long, dolphin-like tail. The other followed, sending an arc of spray shooting upwards, tail slapping against the choppy waves." In a small coastal town, Finn is enduring a winter vacation with his annoying new stepmother, wishing things could go back to how they were, while Sage is enjoying her new home, wishing things would stay as they are. Finn has seen mysterious swimmers in the sea late at night. Then, from the clifftop, first Sage, then Finn, hears an eerie song. Could the local legend of merfolk living amid the waves actually be true? When the new friends meet the magical sea-people, they are amazed and impressed, but the merfolk are hiding a secret. The two human children must put aside their own problems and help in the battle against the young merfolk's ancient underwater enemy before the last of their kind are lost forever. From the author of the much-loved Guardians of the Wild Unicorns, Secrets of the Last Merfolk is an exciting fantasy adventure that reimagines the mythical sea-people as powerful, proud and fearless.
