Execution Order: A James Ryder Assassin Thriller (James Ryder Thrillers)

He’s taken down killers, cartels, and corporations. Now he’s hunting the man pulling every string. James Ryder thought his war with the Richter empire was over. He eliminated the president of Richter Defense Systems, the man responsible for the weapons that wiped out his Delta Force team. But Tobias Richter, the billionaire patriarch, still walks free, expanding his empire while illegal arms flood Eastern Europe and kill our allies. Richter hides behind layers of protection: Pentagon contracts, political power, and a private army loyal to his bloodline. To bring him down, Ryder assembles an unlikely team of a disgraced journalist chasing redemption, an ex-NYPD detective with a score to settle, and an Army CID agent who’s already broken every rule in the book. Their mission: infiltrate Richter's Manhattan fortress and force him into the open. But when the tower assault goes sideways, and Richter escapes, the hunt becomes a lethal game of cat and mouse through the streets of New York and beyond. Execution Order is the pivotal fourth book in the James Ryder assassin thriller series.
