When Y/N Swan returns to Forks to look after their younger sister Bella, they expect boredom—not secrets that twist through the woods like fog. Strange attacks shake the town, Bella hides more than she tells, and the mysterious Cullen family seems to watch Y/N a little too closely. As danger creeps closer, Y/N is forced into a world they never believed existed, where alliances are fragile and trust can be deadly.
