THE PERIMETER PROTOCOL: Zero Second Strike

Every hidden weapon on Earth is about to become visible. All at once. To whoever finds it first. Marcus Reyes has spent four years running from a memory he doesn't have. A disavowed CIA officer, his mind was surgically stripped of one catastrophic night in Vienna - leaving only a recurring nightmare: a stone hallway, a dying man's voice, and a question he can't remember asking. Then a photograph crosses his desk, and the hallway starts getting closer. Dr. Talia Adler didn't mean to end seventy years of nuclear deterrence. She was hunting dark matter. What she found instead was a way to locate any hidden weapon on the planet - instantly, unjammably, for anyone who gets there first. Within days, someone tries to kill her in a Geneva parking garage. Within a week, Marcus discovers the man in his nightmares was her father - and that he made him a promise, eight years ago, that his own government erased from his mind rather than let him keep. Now four of the world's most powerful intelligence services - the CIA, the SVR, Chinese state security, and a Mossad officer with orders she's praying she never has to obey - are converging on two people who know a secret dangerous enough to rewrite the balance of global power. From a black-market broker's warehouse on the Bosphorus to a car chase through Vienna's oldest streets, Marcus and Talia have one chance to expose the truth before someone buries it - and them - for good. The clock isn't just ticking. It's counting down to zero.
