The Hacker

A High-Stakes Hacker Origin Thriller of Conspiracy, Betrayal, and Survival

By: Mark O'Neill

Narrated by: Virtual Voice

She thought it was just another routine hacking job. But in fact she was walking into a war

Katja Liebermann lives for the digital underworld—fast jobs, faster money, and a reputation as one of Berlin’s sharpest freelance hackers. But when the head of a powerful hacker group, called The Circle, drags her into a dangerous government hack, Katja discovers she’s been set up as the disposable pawn in a conspiracy worth killing for.

When Katja uncovers a hidden purge buried deep inside a NATO system, she realises she’s the only one standing between the truth and a world-scale cover-up. The wrong move will get her killed. The right move gets her arrested. Either way, someone wants her gone.

With killers closing in, Katja must choose between surrender, silence, or fighting back with the only weapon she has left—her mind.
