Angel of Death by S. Massery

Griffin:
I’ve been living in the darkness for so long, I’ve forgotten what the light feels like.
Secrecy has kept me alive, because the amount of people who want me dead? Let’s just say it’s a long list. When my identity gets into the wrong hands, the person I hold most dear in the world is thrown into danger. Shedding my darkness and rescuing Hadley from my enemies is an easy choice to make.
If only I didn’t have to rescue her from herself, as well.

Hadley:
My guardian angel—the boy I almost fell in love with—disappeared five years ago.
When he returns, hunting men who want to use me against him, my relief is overshadowed by doubt. I’ve been holding onto my own secrets for far too long, and learning to trust Griffin again doesn’t come easily. He wants to sweep me away to Europe, where I always dreamed of going, to keep me safe.
If only my dream wasn’t about to turn into a nightmare.
