The Debt Collector is Jon Mills’ longest series, running thirteen books from 2015 to 2019. The protagonist works as an enforcer, collecting debts through intimidation and violence for criminal organizations. Each book puts him in a new dangerous situation while building on his backstory and the relationships he forms along the way.
The series ramps up the stakes with each installment. Early books like Vengeance and Reborn establish the character and his world, while later entries like Trail of the Zodiac and Fight Game introduce more complex threats. Mills published the books at a rapid pace, sometimes releasing multiple titles in a single year, which helped build a loyal readership among action thriller fans.
The final books in the series bring the long-running character arc toward a conclusion. Cry Wolf and Oblivion, both published in 2019, close out the series after four years of consistent releases. The Debt Collector remains Mills’ best-known work and the series most associated with his name.
