I never wanted to take a life. Now, I have no choice.
People say that showing mercy makes you strong, but I know otherwise. Mercy only brings pain. It shows that you're weak—that others can touch you without consequence.
I've learned my lesson the hard way. Someone I once loved is threatening my men's lives and tearing mine apart. They think they can control me, but I'm not the same woman they remember.
I gave mercy once. I won't make that mistake again.
Reign of Four is book two of a reverse harem, Russian mafia dark romance duet, which immediately follows the events of book one, Rule of Three. You must read book one before reading book two.
