Sam Cogley

My passion for storytelling began as a child, sparked by the exploits of James Bond and the action films of the 80s and 90s. As I grew, I found inspiration in the literary works of Tom Clancy, Michael Crichton, and Lee Child.

In 2024, I released my debut novel, Shadow Operative, the first in the Adam Knight Thriller series. What began as a single book has since grown into a fast-paced, globe-trotting series spanning five novels...and counting.

In June 2025, I launched a spin-off set in the same universe centering on Penumbra Division, starting with The Last Operator.

In early 2025, I signed a multibook deal with Boldwood Books to launch a brand-new series featuring Dane Winter, an elite ex-soldier turned freelance operative. The first book, Hostile Asset, was released in October.

My second Dane Winter thriller, Collateral Damage, was released in March '26.

And my third Penumbra Division thriller, The Triangle, will be released in early May '26.

Off the page, I’m a devoted husband and proud father to a son and daughter. Without them, none of this would be possible.
