Jennifer Potter And The Marauders (book 3) The New World - Fayally1998

Voldemort is dead, and the wizarding world must now try and put itself back together again. Jennifer Potter is grieving, along with most of the population, for their loved ones who lost their lives in the Battle of Hogwarts.
She also has a new job, an orphan Godson, and her own wedding to plan. But her mind is damaged, beyond repair, as Remus's death sent her over the edge. And even Charlie can't make her see sense.
The war may be over, but the world is not yet free from corruption.There are several Death Eaters still at large, and the Aurors must track them down, before they do any major damage. Jenny may have put that part of her life behind her, but the Aurors want her to re-join them in their fight. Harry Potter and Charlie Weasley must try and keep Jenny on the right path, and stop her going back to what she knows best.
