Joe Hill's NOS4A2 meets Ray Bradbury's Something Wicked This Way Comes in this captivating novel about a father trapped in Knowhere, a deadly border town between life and death, run by the sinister Mister Teeth.

When Roger falls asleep on the train after a long day at work, he's shocked to learn he isn't stuck at the end of the line. Instead, he emerges from the last stop to step out into the rainy gloom...in a place he's never heard of: Knowhere, where monsters roam at night and the only way home is to travel through each of the five ringdoms to the very center. It is only there, at Termina Station, that he can take a train out of Knowhere and return to his wife and children.

But each ringdom has its own twisted logic, and the ticketmaster, Mister Teeth, isn't keen on letting Roger out of Knowhere. With Mister Teeth's son in tow, Roger hopes he has what it takes to puzzle his way out of each ringdom and face his demons in the process. But Mister Teeth is a powerful enemy, and he'll do anything to stop his son from boarding the train at Termina Station.
