Force of Nature by Margot Scott

It was supposed to be our last camping trip, a final sendoff before my daughter flew off to college. Then four men stepped out of the shadows and into my worst nightmare.
I knew what those bastards had in mind before they sat down at our fire. Forcing me to watch as they tormented her wasn’t enough. They wanted to break her, and they wanted me to be the first to do it.
Impossible. I could never harm my own child. But regardless of the sickening betrayal, I can’t help how my body responds. She can’t possibly want this either, so why does it seem like she can’t get enough?
The twisted desire we feel can only be wrong. But in the wilderness, the rules of men no longer apply.
Out here, we play by the laws of nature.

Hunt or be hunted.
Take or be taken.
Kill or be killed.
