If anything, you should read The Edge of Everything for its claustrophobia-inducing caving scenes. I never will go into a cave after reading this book!
That being said, the novel brings little surprises to the "girl meets supernatural boy and falls inexplicably in love with boy" genre. If you enjoy paranormal romance or are a fan of the CW's Supernatural, you'll likely enjoy this book for its unique take on hell. Dog lovers should be aware that the main character's two dogs, Spock and Uhura, are routinely threatened with death. They are used multiple times to show just how bad serial killers/winter/the denizens of hell can be, which gets frustrating pretty quickly.
