Mantis Nights: Book 1 of the Mantis Series

Late at night, while the city sleeps, and the sidewalks are quiet, a man by the name of Mantis Shed walks with his eyes closed. Visions appear and he engages them, becoming one with fantastic worlds, battling mighty warriors, conquering fantastic realms. Mantis chooses when to come and go. It's the perfect escape from a boring world. Then, when visions begin to trap him, losing is no longer an option and winning is a matter of life and death.
