"A novel" - cover.

NASA is building a probe to be splashed down in the Kraken Mare, the largest sea on Saturns great moon, Titan. It is one of the most promising habitats for extraterrestrial life in the solar system, but the surface is unpredictable and dangerous, requiring the probe to contain artificial intelligence software. To this end, Melissa Shepherd, a brilliant programmer, has developed "Dorothy," a powerful, self-modifying AI whose true potential is both revolutionary and terrifying. When miscalculations lead to a catastrophe during testing, Dorothy flees into the Internet. Former CIA agent Wyman Ford is tapped to help Melissa Shepherd track down the rogue AI. The AI is also being hunted by a pair of Wall Street traders, who want to capture her code and turn her into a high-speed trading bot. While being relentlessly hunted, Dorothy has an extraordinary revelation-and devises a plan.
