Counterterrorism operative Scot Harvath dives deep into another world-shattering plot with personal ramifications in "Code of Conduct," Brad Thor's latest thriller.

Harvath is planning to spend quality vacation time with the woman he loves when he receives a plea from the director of CARE International, an organization devoted to helping people around the world. One of its medical facilities in the Congo has been decimated, and the director wants to know why. He only trusts Harvath, so a team is established to infiltrate the site and find answers.

What the team uncovers in the midst of a rescue operation and finding witnesses is shocking. Harvath wants nothing more than to fly home and save the people he cares about from the horror that's about to hit the world.

The true effects of the onslaught and chaos that follow are treated as secondary to how everything relates to Harvath on a personal level, which makes the book a much better read. Thor tackles the fear of terrorism and makes it both a scary and an exciting read. The motivations and rationale behind the threats become both relatable and understandable.
