On a November morning at the University of Georgia, a fraternity brother steps into a busy crosswalk and is struck dead by an oncoming car. More than a dozen witnesses all agree on two things: the driver looked identical to the victim, and he was smiling.

Detective Marlitt Kaplan is first on the scene. A local and the daughter of a professor at the university, she knows all its shameful history. But in the course of investigating this hit-and-run, she will uncover more chilling secrets in the sprawling, interconnected system of fraternities and sororities that empower the university's most elite students.

The lines between Marlitt's police work and her own past begin to blur as she seeks to bring to justice an institution that took something precious from her many years ago. When threats against her escalate, Marlitt must question whether the corruption in her home town has run off campus and into the police force, and how far these brotherhoods will go to protect their own.
