Our heroic teen science prodigies are back for a new mission with the Curie Society, an elite secret organization within which brilliant women can pursue the furthest reaches of their intellect. This time, Eris has returned as well, with startling new tech to wield in its sinister plans!

There's a world of possibilities awaiting the brilliant young scientists of the Curie Society--but what if the designs of their criminally brilliant one-time partner threaten that world? Taj, Maya, and Simone are off to Madrid to help the local Curie Society chapter at a big technology conference, and this sunny working vacation is about to go haywire! Taj's high school friends are also in town for an international E-sports tournament, and she is torn between work and play. With a key member of the team distracted, the nefarious Eris organization sees a golden opportunity to step in and seize the advantage. They're using an AI translator to stoke tensions at the conference, but to what end?

When the plot is uncovered, the Curie Society must use every weapon in their intellectual arsenal--and every member will need to be in play--to defuse a global catastrophe!
