Harriet Potter and the Overwhelming Desire to Punch Lucius Malfoy (гет)

Moments after she strikes down the Dark Lord Voldemort in the Battle of Hogwarts, Harriet Potter is sent back 20 years into the past, her parents seventh year of Hogwarts. With no hope of ever returning to her time and a new, Magic made identity, Harriet joins forces with Slytherins and Gryffindors alike to collect Tom Riddle’s Horcruxes as quickly as possible and finally be done with this gods damned war. No longer a Potter, Harriet is desperate for some kind of family and stability in this foreign time. Is there any chance when Magic made her the biological cousin of the Dark Lord?
