Prey is the thirteenth novel by Michael Crichton under his own name and the twenty-third overall. It was first published in November 2002, making it his first novel of the twenty-first century. An excerpt was first published in the January–February 2003 issue of Seed magazine. Prey brings together themes from two earlier Crichton best-selling novels, Jurassic Park and The Andromeda Strain and serves as a cautionary tale about developments in science and technology, in particular, nanotechnology, genetic engineering, and distributed artificial intelligence.
