Spider Woman.
A Year Later.
Jessica munched on her croissant, and took a sip from her coffee before brushing the crumbs delicately off her work. In the year she'd spent outside the magical world, she had started attending non magical school. If there was one thing her mother had done that Jessica had approved of, it was making sure James paid for a muggle education to ensure her brother and her learnt a bit more than other witches and wizards, about science, maths, and English. Of course, they'd had to be careful, because at that age Mark was conceited, and going on and on about being the boy who lived. To stop this and prevent anyone from finding out about the truth of the family, Lily and James had cast a number of spells to stop Mark from boasting. They hadn't bothered with Jessica, because at the time she was starting to mature, so they didn't bother with her after a month. The spells they'd cast on her and Mark originally was linked to a pensieve that marked the number of times they'd almost, almost, revealed the existence of the magical world.
Jessica, of course, hadn't said or thought a word, so her parents stopped casting the spell on her, but Mark...
Mark had been spoilt by everyone in the magical world, from the Minister of Magic himself, to Albus Dumbledore and the other Light families, and so his head was inflated to grow large enough to encompass the Moon.
The pensieve recorded a top level of 300 times Mark had almost blown their cover. 300. No matter how many times Lily and James told him to keep his head down, Mark couldn't get it into his thick skull to grow up and see the muggles knew nothing of magic, and anything out of the ordinary would mean tonnes of trouble for him and the Potter's prestige, but Mark was confident that being the saviour of the magical world would mean anyone would be happy enough to lick manure of his shoes if he asked it.
In the years since she'd started attending Hogwarts, Jessica had carried on with prearranged and paid for education classes with summer school lessons. Although it annoyed her to do it, Jessica had seen no other alternative but to cast spells on the tutors to stop them from asking too many questions about what she did with her school terms. What she did over the course of the year, her Hogwarts years were added to the coursework and studying of the muggle documents and work. Every holiday she would post the completed work, and go back to Hogwarts with new work. The beauty of being in Ravenclaw was the layout of the private rooms and the common room. Both had private desks with music as an option to help the concentration, and to stop boredom creeping in.
Jessica had planned to leave the magical world no matter what. She'd always enjoyed leaving Potter Manor whenever she was tired of seeing her parents and Sirius and Remus, and the other members of the Order of the Phoenix slobber over Mark. No one bothered her when she left. It never occurred to them that by isolating Mark, they weren't concentrating on Jessica. When Dumbledore had arranged for Mark to spend time in Sirius's old hovel, her parents had jumped for it. With Voldemort back they knew the first thing he would do would concentrate on searching for Mark, but they neglected to take Jessica. She wasn't really bothered, any chance to avoid her brother, the Weasleys and Granger was always going to be welcome.
Jessica frowned as she read the newspapers, and found nothing weird, as in the magical world coming out into the open again. The problem with the Magical world was that they never listened to logic. She'd been buying newspapers all year to see if her words would be listened to, but she doubted it. Magical Britain had and would always be a Dark Lord magnet, and the war would always spill out into the muggle world. Jessica checked her rune necklace and ring, then nodded happily. Both were working.
Knowing that the magical world - Dumbledore - would try and track her using her magical aura, or a comb with strands of her hair on it, Jessica had crafted two special devices to mask her magical aura from detection, and she took great care in maintaining them. If the magical world found her, then there would be trouble. Jessica finished her croissant and swilled down the last of the coffee, before using a napkin to wipe away the excess remains before she looked out towards the city of London, mentally reviewing her long term plans. After converting her trust fund into muggle money, Jessica had used the money to purchase her riverside home and her education proper. She'd also started writing children's books, using her memories of Hogwarts and her time as the sister of the Boy who lived as a template under an assumed name.
Her books earned her enough money to live a magic free life, and she was careful not to reveal much about the real magical world in a fiction book. Jessica was certain someone as smart as Hermione Granger would figure out who'd written the books if she read any of them.
I'm sorry for how short this chapter is, but its only a brief summary. The excitement happens in the next chapter.
