Okay hear me out. I love Caius and I can't find any x readers so I thought I would make one. But with a couple of twists. So this book is a Twilight and Harry Potter crossover with you (the reader) staring as Harry Potters little sister!!!🤗 Bare with me please I get ideas but it's hard for me to put it in words🤣😭. It may take a while for Caius and the reader to meet and actually develop a relationship but as I said please bare with me 😭🤣 The book starts off with Y/Ns first year and Harry's third year. Also known as Harry Potter and the Prisioner of Azkaban
