"What makes a thriller thrilling? Nonstop action, precarious situations, hair-raising suspense, and heroic characters all exemplify the best thrillers on the market." This Reader's Digest post list their editors' choice for best thrillers. I'm providing the link to this list because I was surprised to find that I had read all ten books. (They actually cheated and list more than twenty books.) I'm not sure I would rate them the ten best of all time, but every one of them is pushing hard for the honor.
Take a look. You may find your next book on this list.
