The Sprawl Trilogy is a series of three science fiction books written by the author William Gibson. The trilogy includes the books Neuromancer (1984), Count Zero (1986), and Mona Lisa Overdrive (1988). The stories all take place in the same world and follow different characters as they explore its mysterious technology and explore their own identity and place in that world. The main theme of the trilogy is ultimately about identity and the idea that our own actions can shape our world and our relationships even as technology changes in unprecedented ways. The books all feature cyberpunk themes such as artificial intelligence, virtual reality, and advanced hacking.
