"In The Exphoria Code, MI6 officer and elite hacker Brigitte Sharp foiled a terror attack on London that used stolen military drone software to deliver a 'dirty bomb'. Now Bridge must battle a series of hacks and ransomware attacks, masterminded by someone known only as 'Tempus', who targets politicians and government officials with impunity. When she discovers the campaign is linked to a cyber-attack on the London G20 summit, Bridge is drawn into the dark-web world of crypto-currencies, Russian hackers and an African rebel militia. In another compelling thriller from the creator of Atomic Blonde, MI6 races against time to prevent a disaster that could destroy the balance of global power forever."--Page 4 of cover.
