Cruel Saint (Vicious Empire Book 1) by Luna Kayne

I LET HER GO BECAUSE I WASN'T STRONG ENOUGH TO PROTECT HER THEN. I AM NOW—AND I'M COMING FOR HER. RYDER SAINT Amara is my dark obsession. She was promised to me in a deal she knows nothing about. Four years ago, I sent her away to protect her from the life I live as the son of a crime lord. Now her brother—my best friend—is dead, and though I wasn’t there for him in the end, I intend to look after his little sister. I should stay in the shadows, let her live the life her brother wanted for her, but she’s in trouble in more ways than one, and I’m the only one who can save her… It’s time Amara came home—to me—where she belongs. AMARA SCOTT As far as I’m concerned, Ryder let me go four years ago, and I never looked back. Now he shows up demanding I come home, and I have no choice but to return when he forces my hand. But I’m not that naive little girl anymore, and I’m packing some secrets of my own. I’ll use my time to find out who killed my brother…then I'll destroy them. Even if that man is Ryder himself.
