The Grid

Located in the heart of downtown Los Angeles, the sparkling new Yu Corporation Building is a monument to human genius. It can converse with its occupants. It can forecast the weather. It knows your body temperature, whether you've been drinking or using drugs. It darkens the windows in the noontime glare. It keeps the homeless away at night and lovingly tends the tree that reaches up through its beautiful atrium. Dubbed the Gridiron, the Yu Building is the culmination of art and function. It's also something else: a serial killer.
Something has gone wrong inside the immensely powerful brain of this corporate dream palace. Before the building is opened to the public, one member of a team of brilliant computer programmers dies slumped against his VDT, his eyes burned black. Then a security guard is found with his skull shattered. Now the men and women who know the building best - including its egomaniacal architect and the one person who may actually be able to reason with the computer - know that the building itself is spinning wildly out of control.
Built to survive power outages and the most massive earthquakes, the brain of the Gridiron cannot be unplugged and cannot be outsmarted. For the dozen people who are locked inside, the Gridiron is turning into a living, malevolent dungeon of terrors, where each death is more horrific than the one before, and human survival may be the ultimate achievement...
