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 Penumbra Division book will be available in Mid-November.

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