Jack Orange is a twentysomething guy who works at a place called The Tent packing dirt in boxes and shipping them off to exotic, unheard-of locales. He thinks about his girlfriend, Gina Black, and the ring he hopes to surprise her with. But when he returns home one day, Gina isn't there. He receives a strange call from a man who sounds like he is smiling-Mr. Grin. He says he has Gina. He gives Jack twenty-four hours to find her.

What follows is Jack's bizarre journey through an increasingly warped and surreal landscape where an otherworldly force burns brands into those he comes in contact with, trains appear out of thin air, rooms turn themselves inside out, and computers are powered by birds. And if he does find Gina, how will he ever survive a grueling battle to the death with Mr. Grin?
