True Believer is Book 2 in this series by Jack Carr.
James Reece left his country after spending many years as a SEAL Team operative when he watched as most of his team were blown up and his pregnant wife and young daughter were assassinated by a small political group engineering and overseeing the distribution of an experimental drug to supposedly reduce the possibility of and the intensity of PTSD for military combatants. In other words, this drug was designed to further enhance soldiers to keep them serviceable. However, there was a serious problem with the trial they distributed without the recipients' knowledge. And evidence of that problem had to be eliminated in order to keep the big financial investments turning a profit. When James Reece learned of this secret political program and those responsible for the devastation of his SEAL team and his beloved family, he went on a vengeance-filled killing spree to eliminate every single one of the people involved. After all, he figured he was a dead man too from what he learned about the drug and how it was administered to him and his team. That was his Terminal List.
After escaping to sail the Atlantic Ocean for close to three months, James decides to find a friend's uncle in Mozambique. He is welcomed, fed, clothed, and, after settling in, helps the sanctioned hunting business capitalize on his talents to reduce the terrible consequences of ruthless poachers. When one of the crew is shot by a poacher, James risks everything to expose himself by rushing his friend to the hospital. That saved his friend's life but also exposed where James had turned up.
Found by a former Team member who now works for the CIA, James is offered a deal he can't refuse and is transported to a compound in Morrocco to train in order to return to an operative level. And so begins his re-engagement with the military, with his country, with taking down the very bad guys staging horrible acts of terror.
There is a Russian George Soros-type orchestrating and masterminding the manipulation of perceptions of these acts of terror and a traitor passing him the information he needs to do it. There are innumerable pieces to the convoluted puzzle which do make for a fairly slow entry into the heart of this story. Of course within this turmoil, there are multiple politicians involved in the receiving of funds and providing of favors for the Russian.
Jack Carr has been there, done that, and the redactions that are blacked out in his novels are the real deal. Authenticity is everywhere from the weaponry to the explanations of ops. Once this story starts rolling, it takes off with a rush. He gives his protagonist James Reece all the emotional strain to decide to once again do what needs to be done and trust that the CIA handler really does have his back and will honor their deal. There is success and tragedy and more decisions to be made at the end of this leg of the series, but James needs a little time to do the hard thinking before agreeing to continue down this road.
True Believer shows the enemy in all of his various forms and ideologies making note of how ideas cannot be killed. If you love military thrillers with a reality seen and deftly described in situations and characters, Jack Carr's novels should definitely be on your reading list.
The Glossary at the end is very helpful.
