David Wren

David Wren writes espionage fiction rooted in the world of Critical National Infrastructure, defence procurement, and the quiet, unglamorous intelligence work that keeps systems running – or watches them fail.

His career has spanned management of some of the UK's most significant infrastructure projects, with deep experience in the rail, defence, and energy sectors, along with former service with the British military. He brings an insider's understanding of how large systems are built, certified, and how threats are managed to ensure they are not compromised from within.

The David Carver series draws on this background to explore a distinctive territory: the space where Critical National Infrastructure meets defence intelligence, where the threat is not a bomb but a signature on a variation order, and where the most dangerous enemies are those who were already inside.

Insertion is his first novel. Dormant and Clearance follow.
