David is 11 years old. He weighs 60 pounds. He is 4 feet, 6 inches tall. He has brown hair. His love is real. But he is not.
David, a robotic boy—the first of his kind programmed to love—is adopted as a test case by a Cybertronics employee and his wife. Though he gradually becomes their child, a series of unexpected circumstances make this life impossible for David. Without final acceptance by humans or machines, David embarks on a journey to discover where he truly belongs, uncovering a world in which the line between robot and machine is both vast and profoundly thin.
