She longs for revenge, and she'll do anything to get it.

Desperate to slay the monster that killed her mother, Scarlet is faced with a life-changing choice: to let the strange man who arrives in her hospital room erase her memories, or accept his offer to join an elite agency that not only helps maintain order over the Supernatural world, but trains super-soldiers to help combat them.

For Scarlet, there is no hesitation. She will give anything to avenge her mother—even if it means joining an elite supernatural organization to do so.
