I Found a Circus Tent in the Woods Behind My House by Ben Farthing

Lost in a labyrinth of circus tents...

Dave and his four-year-old, Jacob, find a circus tent in the woods behind their house. A strange voice invites them through the dark doorway.

When they refuse, the tent swallows them.

What follows is a nightmare fleeing through a maze of circus tents. Strange performers lurk inside. They want Dave and his little boy to put on a show. The a shifting figure on a platform high above the trapeze wires.

With Jacob perched in the crook of his arm, Dave determines to outsmart the boss of this dark circus, and escape this horrifying tent.
