Three children off a yacht in New Zealand’s Bay of Islands meet a pair of alternative lifestyle local kids who live on an old barge in the mangroves.

Before long they become embroiled in a battle of wills with an oyster farmer who is refusing to accept the environmental impact of the plastics he is jettisoning into the inlet.

An illustrated multi-layered tale of relationships, independence and determination, which demonstrates that modern children are able to achieve positive change in the world despite their youthfulness.
