Saving the Fallen

It's not every day that a literal angel comes swooping in to save my life.
At first, I thought he was one of them, the army of archangels Heaven-bent on destroying me for my role in saving the Nephilim so they could live a normal life among humans.
But Castiel didn't save me out of the goodness of his heart. Or because there's some greater plan for my life. He did it to get access to my powers.
Because what I have can give him what he most wants-a return to Heaven.
Now I'm running for my life with an angry angel who needs me to hurry up my magic and restore his soul and cursed wings back to their pure form.
But I've never dealt with pureblood angels. Even a fallen one with trust issues and powers that make me stagger just being near him. They're too dangerous to get close to.
But the further we get from our enemy, the closer we get to each other... and the more I want to sabotage the spell that can take away his darkness.
I'm falling for a fallen, and I can't decide whether to push him out of my life for good, or tear his clothes off and risk putting my life in danger that much more.
