A massive rip in the fabric of space and time leaves Space command's deep space fleet stuck on the other side of the rift. Meanwhile alien ships from another dimension arrive on Earth en masse on the other side of the divide. Captain Maguire, a decorated graduate of the Space command academy, whose unorthodox approach to duty is also his strength in a desperate bid to defend commands his starship the Sandawana into the rift in a desperate bid to defend Earth. 
Arriving on Earth he initiates the counter attack to repel the alien ships from Earth.  Other starships of  Space command's deep space fleet arrive on Earth to support the Sandawana's fight against the alien ships. Under the vicious barrage of lasers and missiles from Space command's deep space fleet, the alien ships begin to withdraw to their own dimension. But as they retreat the aliens launch a ground operation and take a senior Space fleet officer captive. 
Captain Maguire is forced to pursue the aliens taking the fight to their home world.

Interdimensional, a starship trilogy

"It would help if the zone could be explored", remarked captain Maguire. 


"Yes it would give a clearer picture of what to expect. We would be able to mark entry points and understand the exit points they lead to", agreed captain Lucinda. 


"Rather than going in like this, it's like shooting in the dark. This is even worse because we don't even have a designated target destination to arrive it", captain Maguire commented with a hint of sarcasm as the starship hurtled through the tightly packed silverish like particles of slithering nothingness as displayed on the starships's main big screen. 


"We could do that but it would take all of Space command's starship fleet and even then, there would be no telling how long the exercise might take", conceded captain Lucinda. 


"I don't think that's a practical given the threat of alien incursions, that would be suicide".
