All the Fae she had been with were dead.

Scarlet earned her title of Fae Slayer, but despite the amount of bodies in her wake, she has no leads on where to find the Fae king. In the aftermath of the Fae invasion, she has three rules for her survival:
Never negotiate.
Never trust a pretty face.
Never tell anyone how she started the apocalypse.
After one of her hunts, she’s cornered by an assassin hired by the Fae king himself. Voss is a Blood Hunter, and he knows Scarlet opened the Fae door, making her the only human capable of ending the king’s rule. He has a proposition: an alliance to kill the king.

Knowing her identity gives Voss the upper hand, and she has no choice but to accept. With two of her rules broken, can she trust the assassin if it means getting revenge?
