Grid

Welcome to the most ingenious building ever designed. Now try to get out alive...In downtown Los Angeles it stands as a monument to man's genius--a glittering, high-tech office tower that washes its own windows, purifies its own air, and even knows which of its employees is using drugs. But now, the building known as the Gridiron has turned malevolent. And its first victim is about to die. From its hardware-jammed computer room on the fourth floor to the 300-foot-high tree that rises in tis atrium, the Gridiron for the men and women trapped inside, there is only one way out: through the raw, human will to survive.
