Ginny Weasley is touched by a shadow. To get rid of it, Voldemort must be killed. And that can't happen without Harry Potter, can it? So she picks him up at privet Drive and takes him to Gringotts. Lord Potter, anyone? And of course Dumbledore's manipulative, and not everyone can be trusted! Harry/Ginny. Rated T for good measure.
When Ginny Weasley finally has enough, she does a simple ritual to go back in time. When she gets sorted into Slytherin House, she makes new friends and allies, all while working towards destroying the Dark Lord, and ignoring her family who have cast her out because of her sorting. No pairing until third year.
Neville Longbottom decides to go back in time after the Battle of Hogwarts, to honor James' and Lily's wish that Harry live a happy life with minal suffering. What he doesn't expect, however, is for the ritual to malfunction and land him on a crazy journey - not in the time that he wished for. Oh, and he gets to meet Death on the way! Rated T for good measure and some language.
In the midst of the battle, Ginny pulls a magically exhausted Hermione aside and they go back in time to when it all began; Hermione's first year. As Lily and Holly Nettle they work together to stop the war before it even began. (No pairings yet)
