Louise Williams is a single mother trying to move on from a troubled past. But her world is turned upside down when she receives a Facebook notification that chills her to the bone: a friend request from Maria Weston—a girl who went missing in high school over 25 years ago, and who’s believed to be dead.
 
As Louise grapples with fear and confusion, the request brings long-buried memories back to the surface. She begins to revisit her teenage years and the cruel bullying that happened at a school party that Maria attended—the last time she was seen alive.
Now, it seems someone knows what happened that night.
 
Someone who is watching. And someone who might want revenge.
 
The novel weaves between past and present, slowly unraveling what Louise and her classmates did—and what it might have cost them.
