Books like Daemon
2009, Daniel Suarez
Daemon and Freedom™ comprise a two-part novel by the author Daniel Suarez about a distributed, persistent computer application, the Daemon, that begins to change the real world after the original programmer's death.
Upon publication of the obituary for Matthew A. Sobol, a brilliant computer programmer and CTO of Cyberstorm Entertainment, a daemon is activated. Sobol, dying of brain cancer, was fearful for humanity and began to envision a new world order. The Daemon becomes his tool to achieve that vision. The Daemon's first mission is to kill two programmers Joseph Pavlos & Chopra Singh who worked for CyberStorm Entertainment and unknowingly helped in the creation of the Daemon.
