Chaos Rises

Gem and her brother Del are half-bloods. They have always been owned or used by someone. Out on a routine mission for Allard to retrieve a lesser demon, things go awry and Del disappears. Allard agrees to help find him, in exchange for Gem snatching an artifact for him. Again, Allard leaves out some pertinent info that lands her in hot water. Can Allard be trusted or is there something else going on. I liked this book, but didn't love it. I was hoping for unique and this wasn't it. I received a copy of this book from NetGalley.
