Harry Potter and the Four Horsemen

Betrayed by the ones he thought he could trust, Harry Potter's life has taken a sharp turn down a dark path. Taking place at the beginning of the Golden Trio's Horcrux Hunt, Harry is captured, tortured, and controlled by those he least expected it from. In the name of the greater good, he has become a slave and powerless to control his fate.
He is eventually rescued after years of abuse, but who is the mysterious savior? If he was captured by the light then is the dark good? Will Harry be the same and what will happen now?

Be wary there will most likely by boyxboy, violence, cursing, and maybe a sad ending.
