Blood Lines (NCIS Series #3)

Commander Will Coburn's NCIS team is investigating the carjacking and assault of a young Marine and his wife. All evidence points to Bobby Lee Gant, son of the notorious criminal and suspected international drug smuggler Victor Gant. When NCIS agent Shel McHenry is wounded during a botched arrest, the team rallies around him even as Victor threatens retribution.
Meanwhile, in west Texas, Shel's father, Tyrel McHenry, struggles with his own demons as buried secrets from a war long since fought come to light. The path he chooses will change his—and Shel's—life forever.
