Thriller and Suspense

Recommendations for all Thrilled and Suspense books go in this thread. Keep us on our toes, afraid of the dark, and peeking around corners! :)

Previously recommended Thriller and Suspense Books:

'Two Little Girls In Blue' by Mary Higgins Clark
The Strain, The Fall, and The Night Eternal by Guillermo Del Toro (director of Pan's Labyrinth and Hellboy) and Chuck Hogan

I read The Strain and The Fall and thought they were pretty good.

The Stand by Stephen King.

I wasn't quite sure if it should be suspense or horror. Either way it was good. I didn't think it was a scary book though, so I thought it was better suited here.
