Trial of the Hunter Moon by Laurel Chase

When I invoked the Trials to save the vampires, I never expected this.
My mother is dead, and my father stands beside the new Queen. She wants it all – the throne, my death, and all the dark magic the vampires once wielded. I’d settle for bloody revenge and a good time.
Good thing I’m not afraid to play dark and dirty to win.
The dangerous relics we’re hunting were hidden for a reason, and handing that power to the Queen could kill us all. I have to survive. I have to win. And to do it all, I have to get my bitter, broken heart to trust again.
Not likely, when fate deals me a sexy thief with the kind of mouth a girl dreams of…smacking, the voice of my murdered mate whispering to me like I’m losing my mind, and a friend-turned-enemy who’s grown into a gorgeous beast of a competitor.
I should have killed them all when I had the chance, because this tension is about to end me.
I’m Kana of Saori Sang, and I’m ready to fight with blood, steel, sins, and smiles.
Welcome to Haret, a magical world parallel to Earth, where all those sexy supernaturals live.
