Award-winning and bestselling author Antony Johnston introduces a major new techno-thriller series featuring an MI6 cyber-espionage specialist. Brigitte Sharp is a brilliant but haunted young MI6 hacker who has been deskbound and in therapy for three years after her first field mission in Syria went disastrously wrong. Despite her boss's encouragement, Bridge isn’t ready to go back in the field. But now one of her best friends has been murdered, and Bridge believes his death is connected to strange “ASCII art” posts appearing on the internet that carry encrypted hidden messages. On decoding the messages, she discovers evidence of a mole inside a top-secret Anglo-French military drone project—an enemy who may also be her friend’s killer. Her MI6 bosses force her back into the field, sending her undercover in France to find and expose the mole. But the truth behind the Exphoria code is worse than anyone imagined, and soon Bridge is on the run, desperate and alone, as a terrorist plot unfolds and threatens everything she has left to live for. Drawing on cutting edge technology and modern global threats, Brigitte Sharp is a highly credible female spy in a truly original and contemporary story.
