Rob Walker is a Special Forces operator created by John Etterlee, a veteran who draws on his own combat experience to write military fiction. The series begins with The Messenger (2021), where Rob comes home from Afghanistan to learn his sister has been taken by a cartel. That rescue mission sets up everything that follows: Rob does not wait for orders when people he cares about are in trouble, and each book makes the danger more personal.
The four books send Rob around the world. Retribution (2022) puts him in Africa, where a botched operation kills half his team and exposes a government conspiracy. Blood Red (2023) moves to Ukraine, with Rob fighting alongside resistance forces in guerrilla warfare against a Russian invasion. An Imminent Threat (2024) brings the fight back to American soil, where a terrorist plot threatens the homeland. Each mission raises the personal cost, and Rob has to weigh duty against survival.
Rob is a soldier first, defined more by what he does than what he says. He is loyal to the people around him and willing to take on missions that most operators would walk away from. The series reads fast and does not pull punches on the violence of modern warfare.
