Three best friends, a lake house, a secret trip - what could go wrong?
It was supposed to be the perfect prom weekend getaway. But it's clear something terrible happened when Claire wakes up alone and bloodied on a hiking trail with no memory of the past forty-eight hours.
Three went up the mountain, but only one came back.
Now everyone wants answers - most of all, Claire. She remembers Friday night, but after that... nothing. And now Kat and Jesse - her best friends - are missing.
That week...
