Keely planned to keep her head down at her new school - she isn't there to make friends or memories, she just wants to be left alone.

In order to get into college, she is roped into a programme that involves camping in the Welsh wilderness with five over-keen try-hards. Her plan is to keep her head down, keep her mouth shut and get through the next few days.

But Keely is running from something. Something that drove her family out of their home and to this quiet town. And when her fellow explorers start disappearing and the bodies begin to pile up, she has to ask herself: did she run far enough?
