Tom Clancy's Support and Defend Mark Greaney

When a young intelligence officer stumbles onto a conspiracy that reaches into the highest levels of American power, he faces an impossible choice: follow orders or follow his conscience. Mark Greaney pulls the action away from the familiar Campus crew to focus on Dominic Caruso, giving readers a tense, claustrophobic thriller where the enemy isn't always foreign and the rules of engagement are dangerously blurred. The stakes are personal as much as political, and the moral weight of every decision lands hard.

Greaney writes with the procedural confidence of someone who has done his homework, and that authenticity gives the pages genuine friction. The pacing is relentless without feeling rushed — he knows when to slow down and let the tension breathe before snapping it tight again. Centering the story on Caruso rather than the broader ensemble cast was a smart structural gamble that pays off, creating a more intimate and emotionally grounded read than a sprawling spy epic might allow. Fans of the Ryan universe and newcomers alike will find this a sharp, satisfying thriller.
