The latest title in Vassiliki Tzomaka's graphically illustrated 'Extreme Environments' series takes young readers on a journey through the world's reefs to discover the remarkable diversity of life they contain. Through a series of detailed landscape scenes, it demonstrates the degree to which flora and fauna depend on each other for survival, and the unique tactics the fish and marine life use to protect themselves.

Focus spreads zoom in on specific species that are especially unusual, clever, or at risk, while infographic illustrations help to quantify the many dangers faced by creatures that inhabit the reefs. By taking a scientific approach to illustrated non-fiction, it raises awareness of the marine environment in a way that makes nature fascinating, engaging and deeply impressive to young children.
