BFFs Tina, Eve, and Lacey come together for a Sweet 16 slumber party that goes sideways when they accidentally summon more than a good time. After Lacey becomes possessed and traps her friends in a fashion catalog, Tina and Eve must find their way out of a totally fabulous new world before the demon overtakes Lacey's body completely. Wendy Dalrymple's YA pink-horror novella is a 90s fever dream that marries the witchy vibe of The Craft with the campy flavor of Jennifer's Body and a neon splash of My Best Friend's Exorcism.
