A howling funnel of destruction screams across the prairie and slams into the sleepy town of Promise, Oklahoma. As the mammoth twister splinters homes, shreds crops, and tosses cars through the air, only three of the town's terrified residents know that an even more malevolent force has come to torment them - and they will not live to tell anyone." "When Police Chief Charlie Grover finds three mutilated corpses in a tornado-ravaged farmhouse, his first thought is that the victims were impaled by flying debris. But his instincts tell him something different. Through solid police work, Charlie proves that they were brutally murdered and discovers that their executioner has left a particularly hideous calling card. Yet how could the killer predict exactly when and where a tornado would strike and use it to cover his tracks? Could this psychopath be one of the storm chasers who streak across the plains in pursuit of the ultimate thrill ride?" "Enlisting the aid of tornado-chasing scientist Dr. Willa Bellman, Charlie will step into a chaotic world of high-tech risk-taking in search of a cunning criminal...one he soon suspects is stalking him - and his lonely, vulnerable teenage daughter. For this is a killer unlike any he's ever encountered before: one who conspires with the awesome power of nature to commit and conceal unspeakable crimes.
