Rayna entered Hell to save Kade. Kade entered to protect Rayna. Both have failed. Centuries of Kade's demons are unearthed when he is brainwashed and used as a Fallen pawn.
In the freezing pits of Hell, Ray is beaten and tortured, pushed to her breaking point. She takes a stand, firing back at her attackers though she's only begun to understand the true strength of her wings. A strength she will need once she uncovers the evils that await on Earth. Together they find solace, alone they will fight.
