On Valentine's Day, as the world basks in the glow of love, he prowls the shadows, his true face hidden beneath a mask that conceals his twisted desires. She's the one he's always wanted but could never have-his best friend's closest confidante. Perfectly vulnerable, alone, and oblivious to the danger that lurks just outside her door, she's the ideal target. Tonight, everything changes. The lines between obsession and desire blur, and he will push her to the edge, making sure she sees him in a way no one ever has.
