NIGHBERT, David F(ranklin)

(1948-)

   US writer who began publishing sf with his Stryker sequence-Timelapse (1988) and Clouds of Magellan (1991)-which engages its thrillerish protagonist first in a complicated TIME-PARADOX tale whose villain tricks him into falling in love with his own mother, and second in a traditional search for the long-gone ALIEN "Builders" responsible for an enormous artifact (BIG DUMB OBJECTS) called The Wheel. Strikezone (1989), an associational thriller, again shows DFN's competence but also a disturbing tendency to rifle his genres for material without showing much concern for establishing a bailiwick of his own.
