Mark the Stars - Operation Humanity

The fight for humanity has begun.  For two generations, the L'quangats have used their superior firepower and strength to subdue humans and force them to live under alien rule. Laws restrict the teaching of human history, art, and culture. To do so means public execution. Bellamy Chambers, along with her brother, Dell, and their friend Zane, were taught by her grandmother, all the things now illegal, in addition to weapons and survival skills-so when the time comes, they can defeat the Gnats and win their freedom. When another hostile force invades, taking the Gnats down, Bellamy and her friends learn that everything they were told while living under the yoke of their alien governors were lies.
The search for truth is a rocky road that leads them straight into danger even greater than the Gnats.
