This is the complete omnibus for readers who want to experience the full opening arc of one of the most compelling techno-thriller series in modern fiction.

Book 1: Helium Heist

KJ20-Ops agent Nash Shields accepts what looks like a quiet embassy role in London. It lasts one day. A stolen artifact from the British Museum leads him into a classified shadow unit hunting a helium-3 device capable of powering cities or blacking out continents. Paired with brilliant curator Calla Cress and chasing a conspiracy that reaches from the White House to the North Sea, Nash discovers the most dangerous lead of all: his estranged brother is at the heart of the plot. A propulsive techno-thriller for fans of The Gray Man and Sigma Force.

Book 2: Fallen Game

When the NSA intercepts chatter about a longevity therapy showing impossible results, Nash is assigned to protect the idealistic researcher behind it. But a ruthless billionaire wants the breakthrough weaponised, and the chase explodes from London to Budapest as Nash and Calla race to stop a man who has rewritten his own humanity. A high-concept spy thriller about power, mortality and the cost of outrunning time.

Book 3: Project Horizon

A forgotten NSA vault. Blueprints for technology that can open doorways to parallel universes. Nash uncovers the impossible and becomes the target of his most dangerous rival, Mason Laskfell, who kidnaps Calla to force his hand. From London's shadowy underbelly to the Orkney Islands and the frozen wastes of Svalbard, Nash must assemble an unlikely team and confront the one thing he has always avoided: trusting others completely. Mind-bending suspense with heart-pounding action.

Book 4: Against the World

Nash has survived every mission KJ20-Ops has thrown at him. Now he walks away. As he uncovers disturbing truths about his superiors, a shadowy organisation targets Calla for her code-breaking abilities and a secret no one should possess. Fugitives together, Nash and Calla take refuge in his remote Colorado hideaway as enemies close in from every direction. The most personal and explosive instalment yet, perfect for fans of Jack Reacher, Jason Bourne and Orphan X.
