At the end of "Order of the Phoenix": No member of the Order received the message that Harry & Co. were at the Ministry of Magic fighting Voldemort and the Death Eaters. Only Dumbledore came to rescue them. Harry got expelled and because he can't go back to the Dursleys he has to live at Grimmauld Place with Sirius (who didn't die). I hope the story is way better than the summary.

At Bill and Fleur's wedding Hermione,Ron and Harry can't flee and Hermione is hit by two curses at the same time. She travels back in time and finds herself in the Marauder's era. I know the story is old, but give it a try please! It's my first fanfic ;
