Odd Thomas Series by Dean Koontz. Odd Thomas is a lovable, humble man with the dangerous gift of seeing those who have passed on, as well as a lot of other visions of forces at play in the spiritual realm that no one else can see. With this gift, Odd uncovers dangerous, evil plots by demented people and puts his life and soul on the line to save them. One of the book series that inspired me to write novels.
