Sensei (Connor Burke Martial Arts Book 1)

In every case, the modus operandi is the same, and the only clue available is a cryptic message scrawled on the wall bearing the signature "Ronin" - the Japanese name for a masterless samurai.

Connor Burke, a part-time college teacher with a passion for the martial arts, is called in to help out with the investigation by his brother, an NYPD detective. With the help of his teacher, the master warrior Yamashita Sensei, Burke begins to follow the trail of clues that stretches across time and place, ultimately confronting his own fears, his sense of honor, and the ruthless killer who calls himself "Ronin".

Combining the exotic world of the Japanese martial arts with the gritty nuts-and-bolts aspects of a murder investigation, Sensei is a fast-paced, riveting thriller that explores the links between people as they struggle for mastery, identity, and a sense of belonging.
