Captain Maguire is forced to pursue the aliens taking the fight to their home world.

Interdimensional, a starship trilogy

"All hands to battle stations, this is a priority one alert!", announced captain Maguire speaking into his hand held communicator. "We shall shortly be entering Drachalian space". 


"Captain, I thought we were to return to Earth", protested captain Lucinda. 


"We are just taking upan unscheduled detour", calmly replied captain Maguire looking at the giant computer monitor's big screen displaying the vacuum of space, littered with stars stretching out in every direction as far as the eye can see. It was a humbling sight, one his soul longed for and loved. A place of relative quiet away from the rat race of life and all that went with it. Here in the vast emptiness, a man could be at peace with his thoughts. 


There were no deadlines to meet, no setting sun to define the passage of time. 


Captain Maguire was enjoying the quiet of the moment, the incredible peacefulness as the Sandawana ploughed through the stars in a hail of streaking lights shooting racing at towards the starship.
