Mirrorheart

A fairy tale retelling based on The Snow Queen.

Artistically-inclined Glory and scientifically-minded Kain were best friends when they were children, but after a falling out in their teens, Kain disappeared. 

He reappears years later, but it turns out that he's been under a strange curse. It has been kept under control by the mysterious mirror spirit Neve, who believes that she could dispel the curse if only she knew more about its origin. Glory, eager to get her friend back, volunteers to help him unravel the truth behind it.

Their journey takes them through a garden of memory, a city of dreams, and a prison of monsters, and it soon becomes clear that Neve herself is more deeply involved with the curse than even she knew.
