Forge of Empire - The Chronicle of the Final Light, #1

Empires are forged in fire and quenched by blood. Avery Shetty joined the Marines to pay for his engineering degree. It meant leaving behind the woman of his dreams. Now it might mean losing his life. When an ancient alien threat rises, Avery finds himself on the front line of a war he can't understand, facing a relentless and merciless enemy. What had been an attempt to create a peaceful galactic union becomes a desperate gambit for survival. This struggle could destroy more than his dreams-it could be the end of the human race. If you're a fan of epic tales of action, intrigue, and war, then you'll love Forge of Empire, the first book in The Chronicle of the Final Light series.
