"Straw Men" trilogy a great read!
 

Not exactly supernatural but genuinely scary and plenty of superb thrills: The "Straw Men" trilogy by Michael Marshall, 3 paperbacks, in print. 1-"The Straw Men" 2-"The Upright Man", 3-"Blood of Angels".

This is a modern action thriller trilogy, sharp, smart, and ol' Stevie King recommends.

As an example, the introductory chapter of the 2nd book "Upright Man" is titled "Yakima" and is one of the most eerie things I've read in a long while.
