Mermaids Are Cool by Sally Squires promotes the theme of taking care of the world's oceans.

From Octarina Octopus and her Octarina Orchestra and her misadventure at the Reef of the Silver Shark to Nobelesta Mermaid's battle to save the ocean creatures from the furiously falling Space Rock, the stories will keep you intrigued.
