All systems are go with author Ruth Owen as she bytes down on this sexy tale of two computer experts who go viral for one another.   "The Terminator." That's what they call security consultant Jack Fagan, a man without a pixel of human compassion. Katrina Sheffield isn't about to let someone with his reputation mess with Einstein, her company's prized artificial intelligence system. She's determined to find the dirt on Jack before his unscrupulous methods sizzle her microchips.   Kat knows she shouldn't fall for a man with no permanent address--and no desire to have one--but when someone hacks into Einstein, she has no choice but to turn to the one man who can help prove her innocence. Jack's price is high. He'll take nothing less than her complete surrender: of her company secrets, her sexual fantasies, and, ultimately, her heart.   Includes a special message from the editor, as well as excerpts from other Loveswept titles.
