Romance Of An Ancient Dreaming City (Josei Manga) by Lily Hoshino

Princess Olga lives inside a gilded cage. Denied the right to choose her future or even whom she may love, she seeks solace and escape in magic and the collection of magical artifacts. Through the enchantment of a golden circlet, she is transported to an exotic land very different and yet so very similar to hers, where she meets Abed, a young woman in similar circumstances. Between them lies a mysterious box with magic to grant them power over their destinies — but how high is the price for Olga’s freedom?
