Sworn to the Shadow God by Ruby Dixon

Adventure.
It’s what my boring life is missing, so when I fall through a portal into another world, I’m excited. Here, I’m important. Here, I’m special.
I find out just *how* special when I meet Death.
Yup. That guy. He’s been exiled to the mortal realm to work through his flaws, and he’s just as spoiled and awful as you’d think. Rhagos, the Shadow Lord, is arrogant and rude and controlling and demands to get his way. He’s selfish. He’s impossible.
He’s also utterly gorgeous. Magnetic. Lonely. And strangely protective of me.
Thanks to a magic bond, I now serve him as his anchor to the mortal realm. It means that I’m his conscience, his guide…and the target for any assassin or glory-seeker. After a few days of this, I’d rather go home than continue on this ‘adventure’. I need a way back to Earth, and fast.
As the world falls down around us and we’re hunted simply for existing, I find myself wondering what it’d be like to serve the lonely god of death…in all ways. To kiss him. To touch him. To bed him.
Except…I’m supposed to be finding a way home, not trying to kiss Rhagos. No matter how tempting he is. No matter how much he stares at my lips.
No matter how much I want it.
