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 seventh Adam Knight thriller, Aftershock, was released in July '26.

My fourth Penumbra Division thriller, Lost Asset, will be released in September '26.

And my third Dane Winter thriller, Cold Justice, will be released in October '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.
