ⓘ About Jon Mills

Jon Mills is an English author that primarily writes thrillers, though he has a tendency to experiment with a few curious sub-genres. Mills, who is from Hampshire in England, first arrived on the publishing scene in 2012 when he released the first title in the ‘Undisclosed Trilogy’. The books made a few waves because of their young adult spin and the fact that they delved into conspiracy theories. Though, the author will admit that he had to deploy a far more rigorous marketing strategy with the ‘Undisclosed’ series than with his other works. Things were a little easier with the ‘Debt Collector’ novels primarily because their plot of an assassin for the mafia who becomes a vigilante was a little more accessible.
