Secrets of The Tally

Meet Allie: she's just woken up in an empty forest with blood on her hands and everything she's ever known wiped from her mind. In her survival-oriented world, people are hunted by vicious predators and it quickly becomes clear that they are specifically hunting her.
Allie's friends and sister have no insight as to why she's a target, and her only clue is a list of tally marks she finds tucked away, detailing how many lives she's saved and how many deaths she's caused. Judging by the amount of ink slashed across the page and the fact that nobody seems to know about it, Allie knows she used to have secrets that need to be recovered.
Without knowing whom to trust, she finds herself drawn to a new stranger in the caves they call home, and even though he won't talk about his own past, he's ready to help Allie recover hers.
The problem now is that Allie's instinct to survive is the only thing strong enough to bring her memories back. Flashes of her old self will only surface to save her from life threatening danger, so if she wants to avoid living as an echo of her former self, danger is what she must seek.
