My Roommates Are Ghosts, Not Friends

I thought my college dorm drama was just roommate fights—until I saw a man climb into their beds at midnight and vanish by dawn. When the truth hit, my 'friends' weren’t human, and the old carpenter who sold me a threshold had a chilling secret: my room sits on a mass grave, and I’m the next target for a supernatural scheme. Now I’m caught between a ghost-refining master, a blood ritual, and the only person I trust is 300 miles away—if I don’t play this right, I’ll be the next girl to disappear.
