You don't need a tail to make a splash! Elecktra is a human mermaid - a mermaid with legs instead of a tail. Abandoned as a tiny baby, she was found and adopted by the merpeople of Mermaid Island, who gave her sea-powder so that she could live and breathe underwater. Now aged nine, Elecktra's desire for adventure is always getting her into trouble! When Elektra's class learn how to dive down and collect magic mermaid fire, Elektra is keen to get more than everybody else! But to do this, she will have to swim away from the safety of the reef and deep deep down to the bottom of the dark and scary sea bed. When Elektra and her dolphin friend Splash dive down, they not only find mermaid fire but a whole of danger as well!
