A Winged Embrace

Emilia Bauer thought college life in Europe would be all fun and games, but when a rare meteor shower ends with lithe, boney-winged monsters emerging from tar-covered pods to wreak havoc on anything and everything in their path, Emilia and her friends run for their lives.
After rendezvousing with the military, they attempt an evacuation to Germany when they're set upon in the narrow, winding streets of the alps.
Under the cover of a snowstorm, Emilia comes face to face with one of the creatures.

Her first thought is to fight for her life, but she soon realizes nothing is as it seems and begins questioning whether leaving her friends behind was the best choice.
Are the aliens the bad guys?

Or are the military personnel her friends sought refuge with the real monsters?
