    Rebellion's End

    Published April 2024.

    In a galaxy where secrets are weapons, one agent must outwit enemies both known and unknown.

    Vaul, a seasoned agent with a dark past, never expected his vacation to turn into a deadly game of cat and mouse. When a stolen military prototype interceptor finds its way to a luxury resort, Vaul stumbles onto a conspiracy that could change everything. The true prize isn't the ship—it's a mysterious artifact, but a dangerous one.

    With rival factions closing in, including a relentless agent mirroring his every move, Vaul must navigate a dangerous web of deceit. Every step could bring him closer to unlocking the artifact's secrets—or plunging the galaxy into chaos.

    Can Vaul ensure the artifact falls into the right hands before time runs out? Or will the forces seeking it destroy everything he holds dear?

    A high-stakes journey of betrayal, power, and hidden truths awaits in this action-packed first book of the trilogy.

  • Resolute Dawn

    Published Feb 2025.

    The galaxy teeters on the brink of chaos—and Vaul is at the centre of it all.

    Weeks after the explosive events of Rebellion's End, a ruthless insurgent force emerges: Resolute Dawn. This rogue faction is hunting down agents, sowing terror, and threatening to obliterate any who stand in their way. The search for the flagship, the Sceptre, continues to elude the Selenis.

    But the enemy is closer than Vaul ever imagined. As the threat escalates, he realises that his recent past—his dangerous exposure to Ethelium, has left him vulnerable. The dark power inside him could be the key to stopping Resolute Dawn—or it could destroy him.

    Can Vaul overcome his inner demons before the insurgents destroy the fragile galactic balance?
