A retired federal agent with more than thirty years of service in law enforcement and the military, Jack served on specialized response teams, worked uniformed and undercover assignments, and spent two decades as a Federal Air Marshal. His career included combat service during Operation Desert Storm as an enlisted soldier, followed by commissioned service as a lieutenant in the U.S. Army National Guard. HORROR FICTION – OCCULT STRIKE TEAM RK Jack’s horror novels blend supernatural horror, military realism, and modern tactical fiction. His Occult Strike Team series begins with "The Devourer From Beyond" and continues with "The Mist From Beyond," following trained professionals as they confront eldritch threats, occult forces, and entities that defy logic, science, and faith. These stories appeal to readers who enjoy dark, intense horror, realistic combat, and high-stakes confrontations with the unknown. The third book, "The Horror From Beyond," will be out in Q4 of 2026. DARK FANTASY—ARGENT THE UNICORN In his dark fantasy works, Jack explores mythic worlds, cursed bloodlines, ancient magic, and morally complex heroes. His award-winning novella Argent showcases a darker, atmospheric fantasy style, blending classic fantasy elements with emotional depth, moral ambiguity, and supernatural danger. Across these stories, heroism is earned not through destiny or perfection, but through the willingness to stand against darkness despite fear, loss, and consequence. The complete trilogy is now available in print (hardcover and paperback), eBook, and audio formats.
