Description: When Cassie Lim's cousin tells her that a stranger's social media profile is full of her photos, she assumes it's some random catfish. She doesn't expect the trail to lead back to her own dorm room. Methodical and clear-headed, Cassie starts posting strategically - narrowing the circle, photo by photo, post by post - until she identifies the person who has been living beside her and lying to her face. But the truth is worse than identity theft. The roommate she trusted most has been running a long game, and the boy Cassie thought was falling in love with her was a piece of it all along. *The Devil Next Door* is a sharp, propulsive thriller about envy, manipulation, and the people closest to us who turn out to be strangers. Perfect for fans of psychological suspense and college drama. *The most dangerous person in your life might already have a key to your room.*
