Enemy of the State by Vince Flynn

When Mitch Rapp goes rogue, it’s not by choice — it’s by presidential order. After Saudi links to a terrorist attack surface, Rapp must dismantle a network of jihadists without leaving any trace of U.S. involvement. From Dubai black ops to desert firefights, Rapp builds a team of mercenaries and ex-criminals, each with their own agenda. The twist detonates when Rapp discovers the real mastermind isn’t the terrorist he’s hunting but a political figure manipulating both nations. Betrayals, double-crosses, and brutal combat drive this entry in the Rapp saga.
