FBI Special Agent Irene Rivers is horrified to learn that because of mistakes made by agents under her command, a murderer and child molester will walk free. But now her worst nightmare has come true: the monster has abducted Irene’s own daughters. With nowhere else to turn, she reaches out to an elite Special Forces operator named Jonathan Grave.

While Rivers has always observed the letter of the law, Grave cares more about results than procedures. Together, they will face a new breed of evil—and pursue a new kind of justice.
