What happens when Cinder and her friends(Iko, Scarlet, Cress, Winter) enter the eerie Lunar Cave? I mean, it's just supposed be a fake, cheesy Halloween attraction all the little kids are afraid of. Right? Wrong! The girls can't seem to leave when they enter. Maybe it is a magical force, moving the girls feet for them and pulling them deeper into the cave. Or maybe it's the weird creature that lurks within it, making the girls fear to leave. Or both... To add to the surprises, the girls meet four boys(Kai, Wolf, Thorne, and Jacin) in the Lunar Cave as well, who went in that night and can't get out. Together, can they leave the Lunar Cave unscathed? And will four relationships bloom after this nightmare ends? Read to find out! This is a Lunar Chronicles Halloween AU set in the modern world! *Disclaimer* Marissa Meyer owns these characters not me!
