Once upon a time in 3 different worlds vastly different to our own lived a girl with great power the same as only .... no one Caoimhe Áine Black lives on a little island in Wales named Cairnholm with her family that includes many peculiar people who even the people of her fathers world might call odd. She will face many evil in her life, but all will be well if she has her friends beside her A Harry Potter world x Mphfpc x Narnia. Oc x Prince Caspian All rights belong to J.K Rowling and Ransom Riggs and C.S Lewis. This will probably be following the plot of the movies as I have only started to read the Harry Potter books and I have only watched the Miss Perigrines home for peculiar children movie and Narnia movies so yeah... Any original characters belong to me
