Rescue on Xavu 6 (Troubleshooters 1)

Hi. I’m Tony. When I pressed 13 in my granny’s lift, it took me and Bea, my girl cousin, down to the secret Earth base of the Galactic Federation. Our Uncle Simon, the Commander of the base, hadn’t returned from the planet Xavu 6. He’d expected a simple trip, but had he hit trouble? We were asked to join the team to find out.
