Special Agent Diane Emerson seemingly has it all: A successful career with the FBI, a close-knit relationship with her twin sister, and deep ties to her city of residence, Allentown, Pennsylvania. When her sister goes missing, Diane’s life is turned upside-down. As horrible as this is, other women are disappearing as well. Diane discovers the tentacle of embedded evil and a thick trail of cybercrime and murder.

When her ex-flame, Agent Alex Kane, is transferred to Allentown, Diane now has to add affairs of the heart to her worry list. But when she herself becomes a target, the affairs of the heart will have to wait as Diane and Alex fight to uncover these malevolent forces—malevolent forces that could wind up killing her.
