Harry Potter: The Other Side of the Mirror

He woke up as Harry Potter. But this isn't the story he knows. A teenage boy from our world opens his eyes to find himself in the body of a young Harry Potter. However... everything seems off. The Dursleys are kind, Draco Malfoy is a friend, and Albus Dumbledore is a tyrant who rules the wizarding world with an iron fist. With little magical knowledge, no allies, and only the fractured memories of a story that no longer applies, Harry must navigate a world where heroes are villains, the oppressed are the "evil," and one wrong word can make you disappear. The Boy Who Lived is about to learn that survival comes at a price...and some truths are darker than any tale. — Description from novelcodex.org
