“HAMMER is a roller coaster of personal conflict, avarice, and retribution across three continents. Joe’s protagonist, Jack Garrett, brings a conflicted, relatable character forced to evolve from the role of victim to that of avenger. Revenge thriller fans…strap in for a bumpy ride.”

“HAMMER is a rollicking thriller that moves from Texas to Bulgaria to South Africa…and shoots right through your nerves as Joe’s dialogue, wit, and artful use of metaphor take readers on an unforgettable journey of greed, despair, vengeance, and love. We haven’t heard the last of Jack Garrett…nor Joe.”

"HAMMER is an electrifying tale of vengeance, resilience, and redemption. This gripping novel transcends the boundaries of the typical revenge thrillers to deliver a heart-pounding and emotionally charged narrative. Joe masterfully combines the world of mixed martial arts with a riveting and complex plot, creating a unique and compelling storyline that keeps readers hooked from the very first page. RELATIVE UNKNOWN is not just about revenge; it is a story of resilience, sacrifice, and the enduring power of the human spirit.”
