There Is No Night
The fair is great fun. You ride the rollercoasters, eat cotton candy, win a small stuffed animal by shooting fish in a barrel. In short you have a brilliant time. And it's not until it's getting dark that you remember that you are supposed to be going to a party tonight at a friend's house.
As you leave the fair you realse that the dome is perfectly aping twilight and the streets are getting dark as you wander towards the party. Suddenly a dark figure leaps at you from out of an allyway.
