But isolation turns to terror when she discovers coded messages carved into the walls—left by the previous occupant who vanished without a trace. As blizzards close in, Claire realizes she’s not alone; someone is watching her from the frozen forest. Each clue drags her deeper into a conspiracy that ties her past to a secret government experiment. Alone, hunted, and cut off from civilization, survival becomes her only story left to tell.
