The Tundra Trials by Monica Tesler

4.0

Jasper, Cole Mira, Lucy, and Marcos are back for their second tour as Earth Force Cadets. Jasper's pod, however, doesn't start off with the rest of the cadets. Instead they are taken to a special base with Waters and Ridders and learn about a new Bounding tool in development that they are needed to test. And when they do meet up with the rest of the cadets it is not at Earth Force Academy as expected. Instead they are being sent to train on Gulaga, the Tunnelers planet. Here all of the pods will be competing in a geocaching competition, testing their bounding skills and the ability to work together. But Jasper and friends realize that not everything is as it seems with the Earth Force, including their rule of Galaga. As they piece together the clues, they realize that their lives may be depend on figuring out who are really their friends and enemies. A solid continuation of the Bounders series. Highly recommended for grades 4 & up. Must read the series in order.
