The Shadow of Merlin

An unprepared girl is thrown face-first into a world of magic and wonder, of intrigue and plots, of Light and Dark—a world ruled by seven ancient, scheming, and immensely powerful families. Harriet Potter must learn quickly—not to excel—but to survive. This is a Dark fem!Harry story. There will be plenty of mythology, worldbuilding, and evil. She's also an Obscurial.
