What’s it about?
The story.
Life on the island is peaceful again — until an injured seal washes ashore with a terrible warning: a Poison Tide is spreading through the sea, driving creatures inland to fight over shrinking safe ground. Roz calms the panic and, discovering that her repaired body is now waterproof, walks straight into the waves to find the cause. Her journey takes her into a breathtaking, dangerous underwater world of strange creatures and an ancient shark, and at last to a vast floating station where humans and machines are pumping poison into the ocean. Faced with the choice between force and peace, Roz must find a way to protect her home without starting a war. Peter Brown's third Wild Robot novel widens Roz's world once more, weaving real questions about pollution and climate into a thrilling, hopeful quest. Illustrated throughout and written in the same clear, fable-like voice, it's an urgent, uplifting story about defending the wild.

Right for your child?
Where it lands by age
Best for 8-11s reading independently, and a strong read-aloud from about 7. It carries a little more scale and environmental content than book one, so it suits slightly older or more confident readers, while adults will value the climate themes.
