Blood of My Sisters

Meet Isla Black. She is a young "Book Witch" not born to a pure bloodline but learns through reading books and practicing spells. When she opens a powerful portal on her own, the Sisters Coven are alerted of her power in the magical arts and whisk her away to Osyth's Abbey. There, she begins to study and learn to master her skills. The other students, except two, are "Blood Witches" - young women born to ancient bloodlines whose power comes more naturally than just through books. They make it clear they will not tolerate Isla -- or the other Book Witches.
Just before Isla's arrival, the Abbey faces an attack by a rogue werewolf. The Coven has their hands full, not just with the werewolf, but with the societal split within their ranks in the Abbey. Against Concilium orders, the Coven takes matters into their own hands. When the Concilium decides to step in with their own plan, they'll learn that clashing with the Coven is never a good idea.
