Court of Command by Milana Jacks

They crashed from the sky. An army of beautiful, mighty, bloody perfections. They wrecked the world until he came. Their Commander. And he has a war plan for us all.

Julia – the mortal
I’m scrounging for food in an abandoned Bel Air mansion when an angel catches me—and I try to kill him. Instead of swatting me like a mortal fly, he strikes the ground with his sword… And I’m transported, wounded and alone, to some kind of Medieval, science-fiction fantasy world.
There must be some reason the archangel—all gorgeous, bloody perfection with massive wings and a deadly kilt—spared me. No mortal is supposed to remember when the angels fell. But I do, and I’m marked with a secret that could turn the tables, and send this beautiful angel straight to hell.

Commander – the archangel
In my world, everything—and everyone—submits to my will. Mortals who retain memories of Before are eliminated. I should eliminate this one, too. But something about her tugs at my very soul. So I’ve decided to keep her.
When I discover she’s a pawn, I discover something else about her. She may be mortal, but she’s not weak. And I’ll fight to my last shred of power to save her before her sanity—and her life—are torn from me.
