Lily The Pond Mermaid by Lucy Fleming

Ponds are lush green places, full of busy life. And some ponds have a secret - pond mermaids, like Lily. Alongside Lily live her dragonfly, damselfly, butterfly, snail, frog and fish friends. But ponds are vulnerable places and Lily worries - a lot - about keeping everyone safe. When a storm hits the pond and everything gets covered in a tangle of debris, Lily feels overwhelmed. But then she finds, bubbling up inside, a little flicker of courage to reach out, talk about her worries and ask for help.
