A well written book about a serial killer that turns out to be more than one. As the plot developed we follow two sisters who are placed in the witness protection program following the murders of three other young women in their area. One of the sisters is stalked after one of the killers is caught and subsequently murdered in his prison cell. While in protection, the sisters become involved in a separate revenge plot for a gang betrayal by a man previously placed in the witness protection in the same town. Just as we think both murder plots have been resolved, this book end with one of the sisters apparently in the crosshairs of yet another killer. To be continued!
