City of Salvation by Marie Maravilla

True delusion was believing that if you pretended your problems didn’t exist, they’d go away on their own. That the monsters living under your bed wouldn’t get tired of waiting for you to crawl into the dark with them.
But they always did.

Running away and becoming someone new would be far easier if the demons of my past didn’t insist on showing up at my doorstep. Turns out that leaving an evil Russian Bratva leader at the altar after helping stage his assassination only pissed him off and made me a target.
I tried blending, but hiding in the shadows under a fake alias is no longer enough.
It should have been easy to keep my distance from the MC member burdened with protecting me. He is just as averse to commitment as I am, yet he’s been the only person ever to see me, even through all the smoke and mirrors I keep between us.

She’s shrouded in secrets, and there’s nothing I want more than to peel back every layer and discover what’s at her core. The glimpses she gives me have me hooked in a way I’ve never experienced before. I’ve always been:
No commitments.
No girlfriends—hell, I’ve never had a female friend.
Yet here I am, wanting to protect her, to be the weapon she wields against her enemies. Because if there’s one thing I have learned during our time together, it’s that the ache in my chest only stops when I am with her.
She’s mine now.
