The Secret Signal: Hal Junior 01 - Softcover

Inhaltsangabe

Hal Junior lives aboard a space station, where his teacher is a robot with literal eyes in the back of its head—and with Hal around, it needs them!

Today is extra special: a supply ship has arrived, and Hal's class is heading aboard for a tour. But when Hal stumbles across a dangerous secret, his robot teacher mysteriously vanishes.

The supply ship's AI proves a surprisingly useful ally, but is it helping him... or using him?

With no one willing to listen to a notorious prankster, it's up to Hal to uncover the truth. But when the danger reaches the entire space station, he'll need more than clever tricks to save everyone.

Zero gravity, an outsized spacesuit and a home-made space cannon. What could possibly go wrong?
