Our heroic teen science prodigies are back for a new mission with the Curie Society, an elite secret organization where brilliant women can pursue the furthest reaches of their intellect, and this time they face a threat more serious and more sinister than anything they've encountered before!

Maya, Taj, and Simone are supposed to be spending their summer broadening their horizons, but their plans take a strange and puzzling turn when the Curie Society's original chapter, at the Sorbonne in Paris, calls on them for help. Daksha, a Society alumna, is promoting cutting-edge science and technology startups at a showcase event, but someone has threatened to stop her and the proceedings. When Daksha is poisoned, the team swings into action to investigate.

Along with new friends from the Paris chapter of the Curie Society, the team is thrown into a globe-spanning quest and a dangerous game of cat and mouse with a shadowy villain intent on controlling the world's wealth through advanced biotech. The Curie Society will need all their specialized science skills to stop this scheme before it's too late!
