Welcome to Coral Kingdom - the home of the Sisters of the Sea! Mermaid S.O.S is a sparkly series for young readers about underwater magic and adventure.
Coral Kingdom is protected by six powerful crystals which fade each year and have to be replaced. Queen Neptuna sends six young mermaids on a mission to fetch the new crystals. Can they battle the wicked-natured Mantora, help the sea life and make it back in time?
Just as the six mermaids think they might just make it back home to Coral Kingdom, they swim across a shipwreck. Holly realises that something is wrong, and it's up to her to be brave and help her mermaid friends. But can she save the home of a family of turtles from danger?
