Hermione realizes things can't stay the same. As she lays dying she sends herself back to 1970 in an 11 year old body. She becomes a part of the pureblooded Prewett family and has plans to attend Hogwarts and change the world. The rating and character relationships might change as I write.
It begins when the 6th years have a free lesson to relax but that's not going to happen if Lily Potter has anything to say about it. Multi-chapter story. LLP/SM fluff.
