Retribution is the conclusion to the 2-book Witness series by bestselling author Christine Kersey. The following book description contains spoilers for the first book. After confessing to the police that she witnessed a murder, college student Courtney Hartford has relocated to what she hopes is a safe place. Hanging over her head is her commitment to testify against Dylan, the gang member she witnessed killing a man, as well as Baldy, a gang member who tried to kill her to keep her from testifying. In addition, her budding relationship with Tyler, who was beaten because of her, has been interrupted. Missing him, but worried about putting him in danger, she wars with herself over whether to convince him to move to where she is now living, or to stay far, far away as his parents advise him. Will Courtney be able to move past the fear she's been living with, or will the gang members track her down and silence her for good? Retribution does not contain any profanity or sexual content.
