TH - 516 | Final Girls by Riley Sager

Ten years ago, college student Quincy Carpenter went on vacation with five friends and came back alone, the only survivor of a horror movie–scale massacre. In an instant, she became a member of a club no one wants to belong to—a group of similar survivors known in the press as the Final Girls. 

Lisa, who lost nine sorority sisters to a college dropout's knife; Sam, who went up against the Sack Man during her shift at the Nightlight Inn; and now Quincy, who ran bleeding through the woods to escape Pine Cottage and the man she refers to only as Him. The three girls are all attempting to put their nightmares behind them, and, with that, one another. Despite the media's attempts, they never meet.

That is, until Lisa, the first Final Girl, is found dead in her bathtub, wrists slit, and Sam, the second, appears on Quincy's doorstep.
