Ariella Potter: Twisted Fate

Ever since third year, Hermione Granger has had a time-turner. Professor McGonagall never asked for it back. During the war, Hermione wears it constantly, never knowing why, but it made her feel more comfortable. After the war ended, Molly Weasley hosts a small celebration party at the Burrow, but what happens when Hermione presses the wrong button on a Weasley Wizard Wheezes test product and it causes an explosion, breaking the time turner around her neck and sending her 22 years in the past in 1976.
There, she meets 16-year-old James, Sirius and Remus, not to mention everyone else. She becomes Ariella Potter, the niece of Charlus Potter and the cousin to James Potter. She set her sights on figuring out a way to go back to her rightful time and not befriending anyone.
But Merlin does that plan go wrong.
What will Ariella do now that she has a soul-bond with a reportedly dead person in 1998, a twin-bond with her best friend's father who also happens to be dead in her rightful time, blood connections to more than one pureblood house, and more friends than she can count?
What will she do now that Voldemort is also on her tail, tracking her every move? Will he strike, or will he wait?
