It’s a race against the clock to save the US financial system from total collapse.

Sydney McEnroe is the VP of engineering for one of the world’s most important financial institutions, and today is her worst nightmare. Her bank is the victim of a vicious cyberattack. She knows who to call. She knows what to do. What she hasn’t accounted for? The key to restoring security is hidden in a former employee’s missing cipher.

 Decades earlier, tech pioneer Gayathri Ramaswamy predicted an attack of this magnitude while building the bank’s systems, but no one listened. She engineered a complex safety protocol—one that could only be discovered by those who truly understood the sacrifices and strength of an immigrant and single mother. As the cyberattack escalates, Sydney must track down Gayathri’s surviving children in order to piece together the mind and method of a misunderstood genius—before time runs out and the global economy is catapulted into chaos.

 A propulsive, emotionally grounded techno-thriller, The Midnight Coder’s Children is a novel about the legacies we make for ourselves, the fragile trust that holds families and civilizations together, and the extraordinary systems built—byte by byte—by overlooked people.
