Beyond the Tunnel - The Wizard Shifter, #1

Adam Stephens is a man with a mission. It has been three years since they chopped that malignant brain tumor out of his head, and he is off on a solo motorcycle camping trip through the Appalachian Mountains. When he rides into the Pine Mountain Tunnel in North Carolina and rides out into another realm-a realm that comes complete with a big sexy grizzly bear shifter, mages, and an evil sorcerer-he isn't sure he isn't lying in the tunnel after crashing his bike.
Can such a world exist? Or is he dreaming? If he is dreaming.it sure is realistic. Along the way, there will be some major hurdles to surpass including no indoor plumbing.and no coffee. A man needs some basic luxuries, correct?
