Audrey & Cassie (Upscaled)

Cassie is your average middle schooler, until she discovers a magical door in her garage and enters a parallel world where everything is exactly the same, but different. She's in charge of a farm, living with a family of horses, but one day, she and Audrey decide to go to school together. Cassie has no idea how to fit in, and Audrey's the daughter of the most powerful woman in the world.
