Congo
Running through the African jungle, you are chased by the beast of the Congo. Michael Crichton's Congo is a fast-paced technological thriller. His use of detail is phenomenal, like his description of a dead man: "Misulu lay on his back, in a kind of halo of blood. His skull had been crushed from the sides, his facial bones shattered, the face narrowed and elongated, the mouth open in an obscene yawn, the one remaining eye wide and bulging."
