Before we Begin This Tale

Tatiana is an 18-year-old girl who has finally done it. She's shifted. Follow Her and her best friend Camila on a journey through the Marauder's Era of the wizarding world.
(I do not own any of the characters besides Camila and Tatiana, all props go to JKR and the Original Harry Potter Franchise)
(This book is based on the shifting community please, no hate towards them)
FYI: I plan on this being a series of books, so this is book one. I POST WHEN I WANT TO
Warning: This may contain fluff, some language, and MAYBE some smut (Idk yet; we'll see)
