This sounds like the exact sort of thriller I will enjoy! Because I especially love it when someone is living alone (or nearly alone) in a cabin in the woods and creepy things are going on. And by the end of chapter 1 the main character, Leah, is already admitting she hasn't seen her roommate Emmy in ages because they work different shifts. And Emmy doesn't have a phone!! So I can't wait to find out what's going on and I hope there's a HUGE twist!
