Danielle Vega, author of The Merciless—soon coming to TV from Pretty Little Liars showrunner Marlene King—is back to chill you to the bones with another creepy tale, and EW has the exclusive trailer for you right here.

In Survive the Night, out July 7, Casey is fresh from rehab, but allows her friends Shana, Julie and Aya to drag her with them to an all-night, underground rave in a New York City subway tunnel. The party is full of drugs and terrifying strangers—but things get even more terrifying when the girls find Julie’s dead body in a dark tunnel, mutilated and being eaten by rats. When Casey and the girls go back to the party, everyone is gone.

Will they find a way out of the endless tunnels before whoever is hunting them catches up? Find out tomorrow.
