These were definitely my favorite dark/not so dark reads. I highly recommend them all! 

(These books include explicit sexual situations, excessive violence, disturbingly sensitive and taboo subjects, offensive language and mature topics. Recommended for age 18+)

Raze by Tillie Cole

Conditioned in captivity to maim, to kill and to slaughter, prisoner 818 becomes an unremorseful, unrivaled and unstoppable fighter in the ring. Violence is all he knows.
 Death and brutality are the masters of his fate.
After years of incarceration in an underground hell, only one thought occupies his mind: revenge...bloody, slow and violent revenge.
Revenge on the man who lied. Revenge on the man who wronged him. Revenge on the man who condemned him and turned him into this: a rage-fueled killing machine. A monster void of humanity; a monster filled with hate.
And no one will stand in the way of getting what he wants.
One woman stripped of her freedom, her morals...her life.
Kisa Volkova is the only daughter of Kirill ‘The Silencer’ Volkov, head of the infamous ‘Triad’ bosses of New York's Russian Bratva. Her life is protected. In reality, it’s a virtual prison. Her father’s savage treatment of his rivals and his lucrative and coveted underground gambling ring—The Dungeon—ensures too many enemies lurk at their door. 
She dreams to be set free.
Kisa has known only cruelty and loss in her short life. As manager of her father’s death match enterprise, only grief and pain fill her days. Her mafia boss father, in her world, rules absolute. And her fiancé, Alik Durov, is no better; the Dungeon’s five-time champion, a stone-cold killer, the treasured son of her father’s best friend, and her very own—and much resented—personal guard. Unrivaled in both strength and social standing, Alik controls every facet of Kisa’s life, dominates her every move; keeps her subdued and dead inside...then one night changes everything. 

'Til Death (2 book series) by Bella Jewel

They say there's a fine line between love and hate. There is. I married a douchebag. I didn't know it at the time. He came in like a handsome stranger and blew me off my feet. I fell madly in love, like the naive girl I am. Then he left me high and dry.
Turns out, I was nothing more than a business plan for billionaire playboy, Marcus Tandem.
He needed to be married in order to obtain his grandfathers business, and I was the poor victim in his path. I believed in what we had, until the truth reared its ugly head. I never meant anything to Marcus. Not a damned thing. With my world spinning on its axis, the girl I once was has long since died.
Instead he left me as this empty, emotionless shell.
I may have made a vow before God to love and cherish him ‘Til Death do we part, but it’s time for me to give back to Marcus, exactly what he gave me.
He has to pay. And pay he will.
