She wants to save the world. The algorithm wants to save the world from us.

Twenty-five-year-old autistic activist Steller Brookfield is determined to stop chemical companies from poisoning the planet—even if it results in collateral damage.

When her team accidentally kills a guard during an op, Steller reluctantly agrees to a mission she believes has zero potential for casualties: sabotage a chemical transport train carrying a toxic product from Jones Chemical Group (JCG) that killed her brother.

As Steller prepares for the op, she questions the trustworthiness of her allies, including Kangaroo—her closest teammate, and Saber—their billionaire benefactor. Mounting evidence suggests that KORA, a chatbot designed to digest current news, is manipulating events from behind the scenes.

After the train sabotage goes awry, Steller must grapple with the devastating consequences and find a new way to fight without becoming the very thing she opposes. To stop KORA from accelerating its scheme to euthanize the 'invasive species' humans, she must evade a nationwide manhunt, reunite her remaining allies, and figure out how to stop an AI that is always one step ahead.
