Doctor and author Robin Cook is widely credited with introducing the word medical to the thriller genre. Thirty-one years after the publication of his breakthrough novel, Coma, he continues to dominate the category he created, including his most recent bestseller, Foreign Body, which explores a growing trend of medical tourism--first-world citizens traveling to third-world countries for 21st-century surgery. Daemon is an ambitious novel, which sets out not only to entertain, which it surely does, but also to challenge the reader to consider social issues as broad as the implications of living in a technologically advanced world and whether democracy can survive in such a world. The storyline portrays one possible world consequent to the development of the technological innovations that we currently live with and the reality that the author, Suarez, imagines will evolve, and it is chilling and tense (on www.thedaemon.com the reader can find evidence that the seemingly incredible advances Suarez proposes could in fact become real). Daemon is filled with multiple scenes involving power displays by the Daemons allies resulting in complete loss of control by its enemies, violence with new and innovative weaponry, explosions, car crashes, blood, guts, and limbs-cut-off galore. As far as computer complexity, Daemon will satisfy any computer geeks thirst. I was thankful for Pete Sebeck, the detective in the book whose average-person understanding of computers necessitates an occasional explanation about what is going on. I came away from the novel with a new understanding, respect, and fear of computer capability. In the end, Suarez invites the reader to enter the second age of reason, to think about where recent and imminent advances in computer technology are taking us and whether we want to go there. For me, it is this thinking aspect of the novel which makes it a particularly fun, satisfying, and significant read.
