Ell Potter and the Prisoner of Azkaban

Told from the perspective of Harry's twin sister, Ell Potter, who is both a werewolf, and Hufflepuff. Follows the Golden Trio around with some attention put on secondary Hufflepuff characters, such as Ernie Macmillon, Hannah Abbot, and Susan Bones, and Ell's adoptive sister Addi, as well as other houses. Full of adventure, and angst. Things are not always as they seem...
