Like every child in Is-Land, Astra Ordott is looking forward to her Security Shot so she can one day do her IMBOD Service and help defend her Gaian homeland from Non-Lander infiltrators. Then one of Astra's Shelter mothers, the formidable Dr Hokma Blesser, warns her that the shot will limit her chances of being a famous scientist—or helping raise the mysterious data-messenger Owleons that Hokma breeds—and Astra reluctantly agrees to deceive the Is-Land authorities and all her family and friends in Or.
Astra grows up increasingly conscious of the differences between her and the other Or-kids—then Lil, an orphaned wild child of the forest, appears in Or and at least she has someone exciting to play with. But Lil's father has taught her some alarming ideas about the world, and Astra is about to learn some devastating truths about Is-Land, Non-Land, the Owleons, and the complex web of adult relationships that surrounds her.

They may be few and far between in the grander scheme, but in the world today there are plenty of places where people live in harmony with the environment, raising families and farming the land without ravaging the planet in the process.
Considering the fossil fuel problem and encroaching crises like overpopulation and climate change, these caring, carbon neutral communities should stand as examples—as promises of what's possible—but more often than not they serve solely as sources of small-minded mockery:
At best, people saw Gaians as cranks, living in a precious little world of our own, sewing our own clothes, home-schooling our children, milking goats. Most people didn't understand the urgent necessity of our way of life. Most people were racing headlong into the Dark Time, their vision of life on earth smeared blind by oil. (p.130)
Naomi Foyle's second novel is set some decades on from an environmental catastrophe which left the surface of the Earth largely "barren [and] volcanic," (p.131) and much as I'd like to say everything changed in the aftermath of the Great Collapse, many people remain set in their ways, however unsustainable. Is-Land, on the other hand—a cooperative country formed by the Council of the New Continents after this terrible tragedy—has seen its membership multiply.
But that's made it a target, hasn't it? And of rather more than ridicule, because there are those nearby nations who want what Is-Land's got, including "crops that will grow and thrive in the unpredictable ecologies of the Regeneration Era [...] cacti bursting with biofortified milk for desert nomads to sow" (p.58) and so on.
Even the lowest-ranking IMBOD officer knew that the safety of Is-Land's greatest treasure could never be taken for granted. Somewhere beyond the faint blue horizon was the Boundary, and pressed up behind it the squalid Southern Belt. There, despite decades of efforts to evict them, hundreds of thousands of Non-Landers still festered, scheming to overrun Is-Land and murder any Gaian who stood in their way. Nowhere was safe. (p.6)
For the foreseeable a period of peace is in place, but come what may, there will be war, and this time, Is-Land intends to be ready to fight for its rights. To that end its finest scientists have developed the Security Serum: a cocktail of hand-crafted Code meant to render its recipients the best soldiers they could conceivably be.
