Dark Matter Empire Series

Ryan Stathis has everything he ever wanted: A family, a nice home, and a career with a government agency designing military aircraft. That is, until one late night at the office ends with him being snatched by an alien spaceship, and he's forced to take command. Thrust into a new universe, Ryan unknowingly holds the key to the one thing standing between Earth, and it’s annihilation. Listen to one man’s journey, as he evades an alien empire's grasp, and searches for a way home. 

The Lithirian Empire have found their long lost home world, and they want it back. Unfortunately for Ryan, that world is planet Earth. Separated by a wormhole that spans the Milky Way, Ryan is desperately trying to organize a group of ragtag aliens to fight back before humanity is destroyed. With time running out, only a high risk insurrection will make he and his team of rebel misfits a real threat against the Empire.
