Dark Passage

Tyson Barrett's dreams want him dead.
An illicit drug trial promises to cure the crippling nightmares that have kept Tyson awake for months, nightmares rooted in the terrible abuse he suffered as a child. Exhausted and near collapse, he jumps at the chance to get his life back.
But Tyson soon discovers a side effect no one could have imagined. Doors are opening between Tyson's nightmares and the real world--and more than memories are coming through.
Now he must face a terror that has stalked him since childhood or risk losing everything he holds dear.
The mind is full of halls. And some of the darkest passages lead to rooms better left closed.
