Galactic Rescue Inc. Vol 1. Prelude

Prelude is Vol.1 of the Galactic Rescue Series.
The tale begins with two friends going for a walk in the Brunei jungle. From there to seeing one of the friends being sliced open from stomach to throat with a 'laser' knife would be enough for anyone! But accompanying that, we find that the two friends are kidnapped to the furthest reaches of the Universe - without a paddle.
Their quest is to return to Earth - but how to do that - with only the empty craft that stole them away; surely beyond their capabilities.
But with the help of a friendly computer-generated voice, they are taught the protocols of interstellar hyper flight. Their adventures whilst searching for Earth takes them to many strange planets and galaxies - all unrecognisable.
Adventures and frights pile up, one after the other, seemingly without any hope of a return to Earth - or is the possibility close at hand? Surely the Universe is not so vast that the Solar System is not visible.
Find out how they get on and enjoy their trials and tribulations.
