This fast-paced thriller is perfect for every horror movie fan—or for anyone who likes a twisty tale that keeps them turning pages late into the night.

What's your worst nightmare?

For Ivy Jensen, it's the eyes of a killer that haunt her nights. For Parker Bradley, it's bloodthirsty sea serpents that slither in his dreams.

And for seven essay contestants, it's their worst nightmares that win them an exclusive, behind-the-scenes look at director Justin Blake's latest, confidential project. Ivy doesn't even like scary movies, but she's ready to face her real-world fears. Parker's sympathetic words and perfect smile help keep her spirits up. . . at least for now.

Not everyone is so charming, though. One horror-film fanatic wants to stir up trouble. There's a girl who locks herself in her room. A know-it-all roommate, "Mister Sensitive." And the one who's too cheery for her own good. Someone always has to make things interesting. 

Things get weirder, and fast. The hostess is a serial-killer look-alike, the dream-stealing Nightmare Elf straight out of Blake's famous film is lurking about, and the seventh member of the group is missing.
 By the time Ivy and Parker realize what's really at stake, it's too late to wake up and run.
