Kael Veyron built his career designing rooms that could take a mind apart safely. He never planned to test that theory on a friend. 
When a restless acquaintance talks his way into a weekend off the grid, what starts as whiskey on a porch curdles fast � a flat tire with no explanation, a compound nobody agreed to, and a man who stops being able to tell the difference between the trees and the walls of his own mind. By morning, Kael isn't hosting a guest anymore. He's the only thing standing between him and an active interstate. 
He gets him home. That's supposed to be the end of it. 
A month later, the calls start drying up. The story going around isn't the one Kael lived � it's worse, and it casts him as the villain in it.
