ADVENTURE / THRILLER. "Darkness Under the Sun." There once was a killer who knew the night, its secrets and rhythms. How to hide within its shadows. When to hunt. He roamed from town to town, city to city, choosing his prey for their beauty and innocence. "Demon Seed." In the privacy of her own home, and against her will, Susan Harris will experience an inconceivable act of terror. She will become the object of the ultimate computer's consuming obsession: to learn everything there is to know about human flesh. "Moonlit Mind." Twelve-year-old Crispin has lived on the streets since he was nine-with only his wits and his daring to sustain him, and only his silent dog, Harley, to call his friend. The city he roams with Harley has secrets and mysteries, things unexplainable and maybe unimaginable. Crispin has seen ghosts in the dead of night, and sensed dimensions beyond reason in broad daylight.
