The Barcelona Threshold

The Barcelona Threshold Truth Unites. Power Resists. The Future Decides. The most dangerous attack on science is not the one everyone can see. At Berlin's National Mansfeld–Koch–Brumiere Institute, Dr. Sarah Koch-Brumiere, Dr. Pauline Koch-Brumiere, and their daughter Julia are preparing for the most consequential presentation of their careers. At the forthcoming international climate summit in Barcelona, they intend to unveil a revolutionary scientific framework connecting the planet's polar oceans, atmospheric systems, and accelerating climate thresholds. Their findings could transform the global climate debate. They could also cost powerful interests trillions. When unauthorized changes begin appearing inside the Institute's most important models, Sarah immediately recognizes the pattern. The alterations are subtle, technically sophisticated, and designed not to destroy the research outright—but to infect it with just enough uncertainty that the Barcelona presentation can be dismissed. Someone inside the Institute is working against them. Behind the sabotage stand two enemies from Sarah's past, now operating from Oslo with the financial backing of international fossil-fuel interests. Their instructions are chillingly precise: compromise the science, corrupt the evidence, and prevent the three presidents from reaching Barcelona if every other method fails. Rather than confront the suspected conspirators, Sarah devises a dangerous counteroperation. She freezes the Institute's three central research projects, forcing the hidden network to react. As encrypted communications multiply and the conspirators accelerate their plans, the Institute's security and scientific teams race to identify every compromised employee before the research—and the people behind it—can be destroyed. At the same time, a remarkable new figure enters their lives.
