As The Hawk Cuts The Heavens: A Novel Of The Cygnus War

From the back cover:

The year is 2124. Earth’s first faster-than-light starship makes its maiden voyage into the unknown and disappears, only to be declared missing for the better part of two centuries. The ship’s historic first mission was supposed to be simple, just a test of the experimental displacement drive. The crew was supposed to spend seven days in the depths of space, then snap back to Earth to prove a concept, and nothing more. 

Instead, they find something impossible. They find something that draws them into a struggle against a horror of meat and metal fifty thousand years in the making. 

 AS THE HAWK CUTS THE HEAVENS is a two-part novel, newly revised, that was originally published as two separate works titled MINERVA (2011) and DARK SALVAGE (2013) respectively.
