Throne of Vengeance by Rina Kent

When vengeance strikes…
You don’t know me, but I know you.
I’m the shadow that creeps behind you without notice.
The moment you see me, you’re dead.
An assassin. A killer. A nobody.
Until I became somebody.
I’ll make everyone who reduced me to a shadow pay.
To do that, I’m willing to risk everything.
Everything except for my reluctant wife.
Rai Sokolov can show me her worst, but this will only end when death does us part.
The road to the throne is paved with loss, betrayal, and blood baths.
To win, we go all in.
Our lives included.
