The Whispering Girls by Jennifer Chase

Dressed only in an oversized t-shirt, with a burlap sack covering her head, the body of a girl swings gently from the branches in the breeze. A newly-lit candle burns on the ground below. The killer was here just moments ago…

Taking a much-needed break in a cabin in the woods with her service dog Cisco, Detective Katie Scott is disturbed by a sharp knocking at the door. Outside, she finds a terrified girl called TJ, begging for help—she says she has found a dead girl in the forest. When they reach the scene, Katie turns to ask TJ further questions, but she has vanished.
At dawn the next day, the body of another girl is found laid out only a mile from the first. To Katie’s horror, she realizes it is TJ. The scene looks eerily similar, with a small shrine below her feet. What kind of monster would do this? And if a twisted serial killer is at work, who is their next victim?

As more bodies and shrines emerge, Katie needs to find the link between the girls and the unhinged killer. But when she stumbles across a cold case that the local police seem determined to keep quiet, Katie realizes danger could be closer to her than she first thought. How much will Katie sacrifice to find the killer and can she stop more innocent lives from being taken?
