Where to Start with They Call Me The Mercenary
If you want to dive into the gritty, action-packed world of Hank Frost, the best starting point is undoubtedly the very first book, The Killer Genesis (1980). Unlike some pulp series where the order doesn't matter, this debut novel establishes the essential backstory of how Hank Frost was betrayed, how he lost his left eye, and the personal code of honor that drives him to survive against all odds. Starting here gives you the emotional foundation for Frost's character before he transitions into his standard global mercenary contracts.

Chronological Continuity & Reading Caveats
Because the series was written by Jerry Ahern under the pseudonym Axel Kilgore in a short four-year window, the chronological timeline closely mirrors the publication order. While the majority of the books feature standalone missions—meaning you can pick up almost any middle volume and enjoy the self-contained action—there are minor continuity threads that reward sequential reading. Hank's relationships, particularly with his reporter girlfriend Beth Stallman, and the escalating stakes of the Cold War build naturally across the books, making a strict chronological read-through the most satisfying experience.
The Legend of Hank Frost: Behind the Eyepatch
Hank Frost is the heart and soul of the series. A former American soldier who served in the Vietnam War, Frost is a skilled survivalist, expert marksman, and wisecracking mercenary captain who wears a signature eyepatch over his missing left eye. A running gag throughout the series is Frost's refusal to give a straight answer about how he lost the eye; whenever a character asks, he invents an entirely new, highly implausible, and humorous story on the spot.
Jerry Ahern brought immense authenticity to the series' combat sequences. As an editor and firearms columnist for Soldier of Fortune magazine, Ahern packed every chapter with meticulous, real-world weapon specifications, survival tactics, and military gear details. This focus on realistic weaponry set the series apart from generic action paperbacks of the 1980s.
The Authors Behind the Pseudonym
Although published under the name Axel Kilgore, the series was created and written by the husband-and-wife duo of Jerry Ahern and Sharon Ahern. The inspiration came when Zebra Books approached them to write a hard-boiled action series with a protagonist who had a physical defect or missing body part. The Aherns developed Hank Frost alongside their legendary post-apocalyptic saga, The Survivalist. While both series share a love for survivalism and firearms lore, they take place in separate universes with no official crossovers or character meetings.
Practical Reader Advice
For modern readers looking to collect these books, be prepared for a treasure hunt. Since the novels were released in the early 1980s as mass-market paperbacks, they can be difficult to find in print. Fortunately, some volumes have seen digital re-releases, but collectors often scour used bookstores and online auctions to get their hands on the vintage Zebra Books editions with their iconic, colorful covers.
