What’s it about?
The story.
In a near-future world battered by environmental collapse, the seas have risen and much of the land is poisoned or lost. Pearl and her little sister Clover live with their father on a floating oyster farm, far from the strict, regulated mainland compound. Pearl loves the freedom of the water and never wants to leave it; Clover longs for solid ground and an ordinary life. When Nat arrives to spend the summer while his scientist mother researches nearby, he carries a secret from the mainland — one that, once shared, could put all their lives in danger. Nicola Penfold immerses readers in a world you can almost taste: salt, sea and the fragile beauty of nature refusing to give up. Beneath the gripping adventure runs a tender story about a family shaped by loss, two sisters pulling in opposite directions, and the hope that a damaged world might still be worth fighting for. Evocative, gripping storytelling with a heart of green.
Fit check
Right for your child?
Where it lands by age
A 9–12 read that rewards a confident, patient reader — the prose is literary and the world takes time to unfold. It works well read aloud from about 8, and the environmental themes and family loss give plenty for older readers and adults to talk about.
