When Bish Ortley, a suspended cop, receives word that a bus carrying his daughter has been bombed, he rushes to be by her side. A suspect has already been singled out: a 17-year-old girl who has since disappeared from the scene. Thirteen years earlier, her grandfather set off a suicide bomb in a grocery store, a bomb her mother confessed to building. Has the girl decided to follow in their footsteps? To find her, Bish must earn the trust of her friends and family, including her infamous mother, now serving a life sentence in prison. But even as he delves into the deadly bus attack that claimed five lives, the ghosts of older crimes become impossible to ignore.
