The Girl Who Never Came Home

My first Nicole Trope book, won't be my last.
Devoured this in just over a day, didn't want to put it down.

Lydia experiences every parent's worst nightmare: her 16 year old daughter Zoe goes on a school camp and never comes home.
The story is told from varying point of views: Lydia, the mother, Jessie, Zoe's sister, Bernadette, the teacher in charge, Shayna, Zoe's best friend, and the villain (with a few extra POVs thrown in when we need them.)
Watching this story unfold makes for a compulsive page-turner!
