Daughter of Broken Things

Tonks has given up on Lupin loving her, but the pain is too much. As she sinks further and further into depression, she turns towards an unlikely alley for help: her Aunt Bellatrix, to numb her pain. But as her ingratiation into the Dark Lord's services begins to grow, her love of another man becomes unacceptable to her new partner, Dominic. Dark Tonks/OC, with shades of Remus.
