I will be honest and say I only made it to Chapter 14 before giving up entirely. The story has a good premise, hence the first star. Unfortunately, it fails to deliver on the expected chills. The suspense falls flat when it could have easily nailed you to the seat, and the tension is none existent.
The problem is the characterisation. I really wanted to feel for them, especially the hikers, but none of them had a personality. Yes, they all had back story, but the execution of the character traits was unemotional when their pasts could have so easily given them strong identities. The character of Hawk for example. Instead of thinking 'Man, I'm so sorry', it was more of oh-hum situation. Internally and externally he was a cardboard cut-out.
As a first draft, the story has potential, LOTS of potential, but as a completed work as it stands, it cannot inject that adrenalin a story of this type needs. I hate to be over critical, writing a novel isn't a walk down a sunny street, but I hope it helps the author in some way.
