Katniss tucked Prim back in to the corner as she listened for the steely sound of approaching aliens or humans that wouldn't look twice before killing others.
Her dark eyes surveyed the terrain as she awaited whatever that was out there to leave.
Prim Rose tugged on her big sister's shirt lightly, "Are they gone?"
"I don't think so." Katniss murmured back.
They croached there for hours before they felt safe enough to move again.
Prim held on to her big sister's hand as they walked on as if danger lurked around every corner as it really did.
Katniss held Prim closely in fear of her little sister being harmed in some way as the alien invasion had led to many human lives lost.
She refused to lose Prim to this or any of this.
Prim is her little sister, and Katniss was willing to fight to the death to perserve her sister's life regardless of when and where that situation may arise.
Prim was all that she had left after their parents were 'hosting' the aliens that had taken over the planet, and Katniss knew not of where Gale went during so, and he may have been transformed in to one of them among the rest though the belief that her childhood friend lived on due to his determination, strength, and his well equiped survival skills in regards to that.
That was the only hope that they had left for those that they'd known other than their hope for the two of them, two sisters, in this cruel world to live on.
