Connor Burke and Yamashita Sensei Books in Order

John Donohue's Connor Burke and Yamashita Sensei novels are martial arts crime thrillers built around a student and teacher whose lives keep colliding with dangerous investigations. The series begins with Sensei, when Connor Burke, a college teacher and committed martial artist, is drawn into a murder case by his brother Mickey, an NYPD detective. What starts as a police inquiry soon reaches into the close, rule-bound world of American martial arts schools.

Connor is not a superhero who happens to know a few moves. He is a serious student, an academic, and an instructor who is still trying to understand the lessons of his training. His skills and cultural knowledge make him useful when a case involves Japanese language, history, ritual, or martial traditions. They also make it hard for him to walk away when someone he respects is threatened.

At the center of the books is Yamashita Sensei, Connor's demanding teacher and a master swordsman. Their relationship gives the series its real through line. Connor wants to honor his teacher without becoming a copy of him, while Yamashita carries a past that repeatedly reaches into the present. Questions of loyalty, authority, and responsibility matter as much as the physical confrontations.

The cases widen as the series goes on. Deshi follows a murder clue written in calligraphy toward rival martial traditions and an isolated mountain retreat. Tengu takes Connor and Yamashita into an international threat involving a renegade sensei and terrorism. In Kage, Connor investigates a writer's suspicious death amid the harsh terrain and smuggling routes near Tucson. Enzan sends him searching for a missing young woman connected to Japan's imperial family, while Keppan brings the focus back to the pressures surrounding a dojo and a troubling death in the yoga world.

The tone is thoughtful but tense. These books make room for training, meditation, and the small rules of dojo life, then put those values under pressure when violence, greed, or old resentments appear. The action is grounded in technique and consequence, rather than fantasy powers or effortless victories.

Read the novels in publication order, beginning with Sensei. Each mystery has its own central problem, but the changing bond between Connor and Yamashita, along with Connor's family and training life, carries forward from book to book.
