The Exphoria Code

“Johnston is a talent to look out for and this, his latest entry into the world of espionage, is a treat.”
Anthony Horowitz

“A fresh voice in spy thriller writing... An engaging character, top flight technological expertise made easy for the reader, fast action and a web of intrigue make this a propulsive read.”
Maxim Jakubowski

“A crackling fuse-wire of a book... Possibly the definitive espionage thriller of the early 21st century.”
Alan Moore

“Could help to redefine the espionage thriller as a literary genre... In Brigitte Sharp he has created the perfect, if reluctant, spy for this troubled modern age.”
Shots Mag

“A fast-paced read that gets the adrenalin surging... If you’re looking for an exciting new heroine and a thriller that will keep you reading long into the night, The Exphoria Code won’t disappoint.”


MI6 cyber-analyst Brigitte Sharp has spent three years deskbound and in therapy, traumatised after her very first field op went badly wrong and caused the death of a fellow officer. Despite her boss' encouragement, Bridge isn't ready to go back in the field...

...Until her best friend is murdered, seemingly in connection to a series of strange internet posts. Bridge is forced to go undercover inside a top secret military project to root out a mole — who may also be her friend's killer.

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.

“A really great, page-turning read.”
BBC Ulster Arts Show

“Johnston does for hackers what Le Carré did for short, fat, office managers: turn them into a spy you can root for... The ending [is] a truly exciting climax.”

“A very enjoyable piece of contemporary spy-fi... I hope someone picks up the rights to Brigitte sooner rather than later and we can see her in action on screen.”
Sci-Fi Bulletin
