The hike
(Book)

"There's a killer on their trail. Burned out by both her marriage and work, Liz desperately needs an escape. More than that, she needs an adventure, a total reset. So when it is her turn to plan the annual vacation with her three best friends, she persuades them to spend four nights wild camping in the stunning mountains of Norway. Following a trail that climbs through lush valleys, towering peaks, and passed jewel-blue lakes, Liz is sure that the hike is just what she needs to get her life back together. But as they stride further from civilisation, it becomes clear that they are not the only ones looking to lose themselves in the wilderness. No cell coverage. No help. No one to hear them scream." --,Goodreads.
