By an Amazon.com customer
IntensityIntensity by Dean Koontz

I couldn't put this book down at all.  My heart was racing as soon as I got a few pages into the meat of the plot.
The Long WalkThe Long Walk by Stephen King
Buy new: $7.99 / Used from: $1.89
Slower paced than a typical suspence/horror book, but it was great none the less.  I couldn't wait to see how it was going to end or if it would end.
RingRing by Koji Suzuki
Buy new: $19.96 / Used from: $0.95
A nice mystery wrapped up in a supernatural package.  Better than the American version of the movie.
ShatteredShattered by Dean Koontz

Great fast paced story.  I finished it during a few hours of a power-outage at work.  Great chace story.
