RoboPack (en Inglés) - Geoffrey Moehl II

Two rival siblings. Two high-tech companion robots. One neighborhood mystery that forces them to work together.

Twelve-year-old twins Alex and Mia agree on absolutely nothing. Alex builds chaotic wearable inventions. Mia constructs flawless, precisely measured models. When a catastrophic collision involving a smoking battery pack and flying glitter glue destroys both of their projects, their exhausted parents sign them up for a corporate beta test that changes everything.

Enter RoboPup and RoboKitty. These cutting-edge robotic pets from PawPrint Robotics seem like the perfect distraction. There is just one massive catch. The robots are locked in a cooperative tether mode. If Alex and Mia wander more than twenty-two feet apart, their new metallic pets freeze like solid statues. To unlock the robots' true capabilities, the twins must prove they can actually get along.

But when the robots start acting strangely, tracking a mysterious rogue frequency and printing cryptic treasure maps, Alex and Mia realize this beta test is not a simple behavioral exercise. Something hidden in the shadows of Gearford is broadcasting a desperate signal.

To solve the puzzle, the twins will have to do the one thing they swore they would never do: trust each other.

A thrilling middle-grade science fiction adventure full of heart, humor, and high-tech mystery.
