Worker robots keep the high-tech town of Terabyte Heights humming, but ten-year-old George Gearing is the only one who has a robot for a best friend. When his scrappy but beloved pal Jackbot is hit by a car, the whiz kid re-engineers him with fancy parts from state-of-the-art TinkerTech Laboratories. Jackbot's astounding new skills far exceed anything George—or even TinkerTech's head of robotics—could ever have imagined. Will the villainous Dr. Micron destroy the whole town to see his tech-driven dream realized? Not if George can help it . . .

In the second installment in the Robots Rule series, George is thrilled to score his dream job at Tinker Tech Industries. But he and his best pal Jackbot soon realize that something does not compute. Gizmos and gadgets combine with mystery-by-the-megabyte in this rollicking robot adventure for readers ages 9 to 12.

Thanks to the eleven-year-old robotics whiz kid George Gearing and his best buddy, Jackbot, the evil Dr. Micron is finally behind bars. But life is hardly back to normal. With TinkerTech closed down for investigation and the townspeople abandoning their own beloved robots, things in Terabyte Heights have taken a turn for the worse. Even George himself is in trouble. Despite finally knowing the truth about Project Mercury, he's still no closer to being reunited with his parents. There's only one person who can save them. But if George enlists his help, who will save everyone else when the battle of the bots begins?
