In the Serpent's Game. The Rourke Correlation, #2

She took the oath. She meant none of it. Vivienne Rourke is now Secretary of State - and the most dangerous person in the world. With the Seraph Initiative, she has built a surveillance machine that reaches into the private lives of allies and enemies alike. She has silenced senators, buried evidence, and used the highest office in the land as cover for a shadow empire forty years in the making. But somewhere in the shadows she cast, something is waking up.
The people Vivienne discarded - a grieving widow with a library book and a secret, a nephew whose loyalty is finally cracking, a disgraced senator who still believes in the truth - are moving pieces on the same board she thought she controlled. The serpent has reached the throne. It hasn't noticed the knife at its back. In the Serpent's Game is the electrifying second installment of the series - a story of institutional corruption, quiet resistance, and the moment when powerful people make their first, fatal mistake.
