Last of Daylight: Vast Collective Book 1

In 2006, Earth faces an invasion by mythic aliens from the planet Cinder. 

Trained by a human-sympathizer and traitor to his own kind, Rayne and her unit of teenagers find themselves in a desperate struggle against the lethal invaders.

The advanced alien army is led by the righteous King Nox–dedicated to his relentless pursuit of humanity's subjugation. By day, his human followers prepare for the invasion at his command. And by night, he visits Rayne's dreams to weaken her resolve.

Exhausted and wrung-out, the unit of fighters confront the invasion head-on. If they fail, Earth will fall under the shadow of Nox's revenge, and Rayne will lose everything to the dark king's sinister machinations.
