Hide and Seeker

Justin knows that something is wrong with his best friend.
I WENT UP THE HILL,
Zee went missing for a year. And when he came back, he was … different. Nobody knows what happened to him.
THE HILL WAS MUDDY,
At Zee’s welcome home party, Justin and the neighborhood crew play Hide and Seek. But it goes wrong. Very wrong.
STOMPED MY TOE
One by one, everyone who plays the game disappears, pulled into a world of nightmares come to life.
AND MADE IT BLOODY,
Justin and his friends realize this horrible place is where Zee had been trapped. All they can do now is hide from the Seeker.
SHOULD I WASH IT?
